The latest news on the foamed concrete agent, concrete additives, white cement, clc blocks and more.
In recent years, foam concrete blocks (also called cement foam blocks) have been widely used and promoted as a new type of self-insulating wall material. Foamed concrete blocks have different properties according to their own density. The reason is the ratio of foaming agents in the production of foamed concrete.
As an important part of the process flow of the cement foaming block production line equipment, the ratio and formula of the cement foaming agent are very important. At present, most of the foaming agents used in cement use anionic surfactants. The advantages of this foaming agent are that the foaming speed is very fast and the amount of foam is large. This is also the reason for the current popularity, but it stabilizes the foam. The time is short, and the defoaming time is also very fast.
It is understood that there are more than 10 kinds of anionic surfactants that can be used as foaming agents, but the most commonly used, lowest cost, and most readily available are alkylbenzene sulfonates. Its representative is sodium dodecylbenzene sulfonate. The synthesis process of sodium dodecylbenzene sulfonate is relatively simple. At present, propylene is mainly used as raw material to first polymerize into propylene tetramer dodecene (C12H24), and then copolymerize with benzene to form a complex mixture of dodecylbenzene. The oleum is sulfonated to dodecylbenzene sulfonic acid and neutralized with 1 sodium hydroxide to form the sodium salt.
Fast foaming and large foam volume are the outstanding advantages of sodium alkyl sulfonate and the main reason why it is welcomed by some people.
However, just like many synthetic surfactant foaming agents, sodium alkyl sulfonate is easy to foam and difficult to store. Its foam rises quickly, but it disappears quickly. The stability of the foam is relatively poor. After the foam is initiated, it will all disappear in tens of minutes, and it is not easy to keep it. Even if it is combined with a foam stabilizer and other technical measures are taken, most of its foam will disappear in about 30 minutes. After the bubbles are made, we will clearly see its bubbles burst quickly one by one, and can hear the sound of bursting bubbles. The originally very small bubbles will quickly merge into larger and larger bubbles.

What are surfactants, and how do they work?
Surfactants belong to a class that reduces surface tension. They can be adsorb on interfaces such as gas-liquids or liquids-liquids. By doing so, they change the properties and affect the stability, wettability of the interface. Surfactants can be found in many fields including industry, agriculture and medicine. They also play a role in energy production, environmental protection, textiles and food.
What is the structure of surfactants in their basic form?
The basics Structure of surfactants The hydrophilic groups and the hydrophobic ones are present. Hydrophilic group are usually polar, like sulfate or carboxyl groups. These groups can interact with the water molecules. Hydrophobic hydrocarbon chains, like alkyl,aryl and lipid groups have long nonpolar chains. They can interact with organic molecules. By embedding this hydrophilic-hydrophobic structure into the interface, surfactants can reduce interfacial tension and make liquid surfaces easier to wet.
Types of Surfactants
The different types of surfactants can be classified according to their charge and molecular properties. Depending on their molecular structures, they are divided into straight-chain, branched-chain, fluorine containing, and nonfluorine containing surfactants. They can be classified according to the charge.
Synthesis Methods for Surfactants
The main synthesis methods for surfactants include the direct method and the modified method. Direct synthesis is a method that connects hydrophilic to hydrophobic groups. The molecular structure, properties and reaction conditions are controlled by changing the raw material and reaction ratios. The modified synthesis is a method that introduces new groups or modifies existing groups in order to produce surfactants with certain properties and functions.
Characteristics and uses of surfactants
Surfactants, a group of compounds with many applications, have the following features:
Special molecular structures:
The molecular structures of surfactants consist of two parts, hydrophilic and Hydrophobic groups. The hydrophilic group interacts with water molecules. While the hydrophobic can interact organic molecules. The special molecular structures of surfactants allow them to reduce the surface tension and change the surface properties.
High adsorption capability:
Surfactants have the ability to adsorb strongly on the liquid-liquid, or gas-liquid interfaces. They can thus change the nature and function of the interface. Surfactants can reduce interfacial friction by adsorbing on the interface.
Surfactants have the ability to automatically align themselves so that hydrophobic groups face inwards and hydrophilic ones face outwards at the liquid interface. This orientation allows for the surfactant's interfacial strain to be reduced, leading to a more stable and uniform liquid surface.
Surfactants reduce surface tension, making liquid surfaces more wettable and permeable. The ability to reduce the surface tension of a liquid gives surfactants an extensive range of applications, including detergents and pesticides. They can also be used in cosmetics, oil, textiles, coatings, food etc.
Wetting & Penetration
Surfactants improve the wetting and penetration properties of liquids. This wetting effect and penetration gives surfactants an extensive range of applications, including detergents and pesticides.
Surfactants that produce foam can have a foam-stabilizing action. This foam effect can be used in many different fields including detergents and personal care products.

The water-reducing agent should be used with concrete admixture, which will reflect the water-reducing effect. Cement quality is therefore a direct factor of the water reducing agent.
When dealing with different types of "problem" cements, different strategies are required.
High alkali cement
High-alkali is a cement type with a large amount of alkali. Alkali in high-alkali is usually higher than that of conventional cement.
The high-alkali cements have a high degree of alkalinity. This can impact the performance. High-alkali Cement can encourage the setting reaction, which is beneficial to the early development of strength in concrete. High-alkali Cement can also increase the fluidity of cement, making it more workable and easier to pump.
But there are also some issues with high-alkali clinkers. As an example, high alkali cements can reduce the efficiency of water-reducing agents and cause concrete to lose its slump faster. High-alkali cement may also lead to corrosion and carbonation problems in the concrete.
High-alkali Cement can benefit from water-reducing agents that contain a higher content of sodium sulfate. High-alkali cement contains a high amount of alkali, which accelerates C3A's dissolution. Sodium sulfate reacts with C3A, forming AFt crystals. This can improve the fluidity in cement mortar.
Low-alkali sulfur-deficient cement
Low alkali-sulfur cement is a cement with a lower sulfate level than normal cement. Ordinary cement is high in sulfate. It reacts with water and the sulfate forms crystals that cause cracking.
Reduced sulfate cement reduces the impact of the Alkali-Silica reaction (Alkali-Aggregate reaction) in Concrete by reducing its sulfate contents. The alkali silica reaction is a reaction between the cement and the aggregate that causes expansion and cracking. The use of low-alkali cements that are sulfur-deficient can help reduce this reaction, and increase the durability and life of the concrete.
Due to the lower sulfate contents, water reducers work less well with low alkali-sulfur cement. Water-reducing agents can cause concrete to lose slump quickly if they are used in excess. In this case, the conventional method of using water-reducing agents may be ineffective. Instead, it is recommended to choose a water reducing agent that contains sulfate.
High C3A cement content
Cement with a high C3A-content is one that has a higher content of C3A. C3A is a mineral present in cement, which reacts to water and forms an expansive substance. C3A cements are characterized by a high early strength as well as a shorter setting time. They are ideal for projects requiring rapid strength development and rapid setting.
Cement with high C3A levels can cause some problems. C3A and sulfate react to form sulphoaluminate. This can cause concrete to expand or crack. In humid environments, cements high in C3A are susceptible to producing corrosive calcium-sulfate precipitates, which can have a negative impact on the durability of concrete and steel structures.
Cement with high C3A will have a greater ability to bind water-reducing agents. This will result in a reduction of the fluidity of concrete and its slump. If you are using water-reducing agents, choose a water reducer containing high sulfate content or a slowing agent with hydroxycarboxylate. These will help to reduce C3A adsorption and improve concrete fluidity.
There are two types of products that reduce water: naphthalene and polycarboxylic acids. The main difference in water reduction is the naphthalene. It is high-performance, while polycarboxylic is high-efficiency. For general foam concrete, the naphthalene cubic addition is between a few hundred to a kilogram.
Lithium stearate is a crystalline form of lithium.
Lithium stearate has the chemical formula LiSt. It is a white powder that is solid at room temperatures. It is highly lubophilic and forms high light transmission at low concentrations. This compound is only slightly soluble when heated to room temperature, but it dissolves readily in organic solvents including acetone and ethanol. Lithium Stearate is stable and thermally safe at high temperatures because it has a melting point and flashpoint. The lithium stearate also has good chemical resistance and is resistant to acids and bases, as well as oxidants, reductants and reducing agents. Lithium is less toxic than other metals, but should still be handled with care. An excessive intake of lithium can lead to diarrhoea or vomiting as well as difficulty breathing. Wearing gloves and goggles during operation is recommended because prolonged exposure to lithium can cause eye and skin irritation.
Surfactant: Lithium Stearate Surfactant, lubricant, and other ingredients are used to make personal care products like soaps. It has excellent foaming properties and good hydrolysis stabilty, resulting in a gentle and clean washing experience.
Lithium stearate has an important role to play in polymer syntheses. It can be used both as a donor and a participant in the formation of polymer chains. These polymers have good mechanical and chemical properties, making them ideal for plastics, rubber fibers, etc.
Lithium stearate can be used in cosmetic formulations to soften and moisturize the skin. It enhances moisturization, and makes the skin feel softer and smoother. The antibacterial and antiinflammatory properties of lithium stearate can also help with skin problems.
Paints & Coatings: Lithium is stearate can be used to thicken and level paints & coatings. It helps control the flow a coating and its properties. It is resistant to weather and scratches, which makes the coating durable.
Applications of lithium stearate include drug carriers, excipients, and stabilizers. It can enhance the stability of medications and also improve their taste and solubility.
Lithium stearate has many uses in agriculture, including as a carrier for fertilizer and a plant-protection agent. It increases the efficiency of fertilizers and improves plant disease resistance.
Petrochemicals: In the petrochemicals industry, lithium stearate may be used as an lubricant or release agent. As a catalyst in the cracking of petroleum, lithium stearate improves cracking yield and efficiency.
Lithium stearate production method :
Lithium stearate can be synthesized through a series if chemical reactions. In order to get the lithium metal reacting with the stearate, they are heated together in an organic solvant. After washing and drying, the pure lithium-stearate product is obtained.
Following are the steps for synthesis.
(1) Lithium metal and stearate in organic solvents, such as ethanol heated stirring to fully react.
(2) The reaction solution must be cooled in order to precipitate lithium stearate.
(3) Wash the crystal with water and remove any lithium stearate particles.
(4) The dried crystals are used to make lithium stearate.
The benefits of chemical synthesis include a matured process, high product quality and efficiency. However, organic solvents have an environmental impact and waste is generated during production.
Methode de fermentation biologique
In biological fermentation, microorganisms such as yeast are used in the medium to produce lithium. This method works on the principle that microorganisms produce stearic and react with metals (such as lithium) to create lithium stearate.
These are the steps that you will need to take in order to produce your product.
(1) The microorganisms will be inoculated onto the medium that contains precursors for fermentation culture.
(2) The filtrate is used to produce a solution of stearic acetic acid.
Add metals (such as the lithium ions) into the solution with stearic to ensure that they fully react.
(4) The reaction mixture is separated, then washed and dried.
The benefits of biological fermentation include environmental protection, less waste discharge and a longer production process. However, the conditions for production are also higher.
Prospect Market of Lithium Stearate:
The application of lithium in personal care will continue to play a major role. It plays a vital role as a surfactant in soaps, cosmetics, shampoos, and body washes. As people's standards of living improve and the cosmetics sector continues to expand, lithium stearate demand will gradually rise.
Second, the use of lithium stearate for polymer synthesis has also increased. It can be used both as a donor and a participant in polymer chain formation. As polymer materials science continues to develop, the demand of lithium stearate increases.
Lithium stearate's application in agricultural, petrochemical, pharmaceutical and other fields is also growing. In the pharmaceutical sector, lithium stearate may be used as a carrier, excipient or drug stabilizer. In agriculture, the lithium stearate is used to protect plants and as a carrier for fertilizers. In the field of petrochemicals, lithium isostearate may be used as an lubricant or release agent. In these fields, the demand for lithium will increase as technology advances.
But the outlook for the lithium stearate market is not without its own challenges. In order to produce lithium stearate, it is necessary to use lithium metal. This increases the production costs.

In the UK, more than 100 schools were closed because of the danger of collapse
In the UK, many schools use RAAC (autoclaved aerated cement) This is a concrete material that is lighter.
In 2018, the roof of a school in southeast England collapsed. It was later discovered that RAAC had been used for the roof as well as the buildings. This raised safety concerns.
BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.
Reports indicate that the risk of building collapse is not limited to schools, but can also be found in hospitals, police station, courts and other public structures. RAAC material has been found.
The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.
According to NHS, RAAC has been detected in 27 hospital building.
The NHS chief has been asked for measures to be taken to prevent collapse.
BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.
The Independent reported Jonathan Slater a former senior education official, who said that Sunak, Prime Minister in 2021, approved budget reductions to build schools.
Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak, then the chancellor, only provided PS50 million per year.
The report also states that despite Sunak having promised to renovate at least 50 schools every year, in the main reconstruction plan of the government only four schools were renovated.
The British National Audit Office chief also criticised this crisis. He claimed that the Sunak government had adopted a "plaster-method" of building maintenance.
He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".
Paul Whitman is the secretary-general of National Association of Principals. He said that the public and parents would perceive any attempt to blame individual schools on the government as "a desperate move by the federal government to divert its attention from their own major errors."
Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for the situation. "No matter what you do to divert or distract, it won't work."
London Mayor Sadiq khan said that the government should be open and transparent. This will reassure parents, staff, children, and others.
BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?
1. The cement problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement, leading to concrete hardening and cracking.
2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.
3. Construction speed
4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in the future. Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.
5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation rates of the surface concrete are accelerated. This results in cracking on the surface. Concrete constructions are most likely to crack in summer or winter due to the temperature difference.
Add anti-cracking material. A variety of inorganic composite materials can prevent cracking more than 80% foam concrete. Add 2-3 kilograms of anti-cracking per cubic meter.
CLC Blocks and foamed Concrete, two new energy-saving materials that are environmentally friendly, lead the construction industry reform.

We often see concrete used on construction sites and in home improvement. However, you may not know that adding a water-reducing agent to concrete is a very important step. So, why do we need to add a water-reducing agent to concrete, and what is the function and mechanism of this additive? Next, we will reveal the answers for you.
First of all, let us understand what is water water-reducing agent.
Water reducing agent is a chemical additive, and the main component is a surfactant. It can greatly reduce the amount of water required for concrete, thus improving the strength and durability of concrete. Using this additive can save the amount of cement, reduce the cost of concrete, and improve the quality of construction.
So, what's the purpose and function of the water-reducing agents?
Particularly, they include the following elements:
1. The effect of surfactants on water is reducing The surfactant that is contained in this water reducing ingredient may be applied to the surface of cement particles, causing them to become more dispersed, thereby reducing the demand for water in the concrete.
2. Dispersing effect Water-reducing agents will make the water within the concrete spread more uniformly, which can prevent the possibility of drying locally and settling.
3. Reduced water-water absorption: These agents reduce the amount of pores present in concrete, thereby improving its permeability and endurance.
The development history of water-reducing agents:
1. The first generation of water-reducing agent
Ordinary water reducing agent (water reduction rate ≧ 8%), also known as plasticizer; the main representative of the lignosulfonate system (sodium lignosulfonate, calcium lignosulfonate, magnesium lignosulfonate, etc.).
2. The second generation of water-reducing agent
High-efficiency water-reducing agent (water reduction rate ≧ 14%), also known as superplasticizer; the main representative of the naphthalene system, melamine system, amino sulfonate system, and aliphatic system.
3 .Third generation water reducing agent
High-performance water-reducing agent (water reduction rate ≧ 25%); the main representative of polycarboxylic acid water-reducing agent, which can be divided into early-strength type, standard type, and slow-setting type.
In short water-reducing agent play an important role in concrete. It will not only increase the durability and strength of concrete, but also reduce concrete needed and cut costs. This is why water-reducing agents are an essential chemical ingredient in construction.

concrete additives are substances that are added to concrete before or during the mixing process. They can lower construction costs and alter the properties of hardened concrete. They are usually liquid and are available in a ready-to-use form, which means they can be mixed into concrete at the factory or on-site. They are available in different types and have unique characteristics to serve specific needs. Some of the most common concrete additives are water reducing admixtures, air-entraining agents, concrete deflocculants, set retarding admixtures and coloring admixtures.
Water reducing admixtures are used to reduce the amount of water needed in concrete mixes without affecting its consistency. They make concrete more workable and are especially useful with larger projects. Some of the most popular water reducing admixtures include polycyclic derivatives and phosphates.
Another type of concrete additive is an early strength-enhancing agent, which helps the concrete develop its initial strength faster. This is a great benefit when working in cold weather since it allows finishing operations to start sooner. This type of admixture is typically made from silica dust, which is created as waste during the manufacturing of ferro-silicon and silicon metals. It also has special pozzolanic properties, which give it a high interaction with water-reducing and plasticizing admixtures.
Retarding admixtures slow the chemical reaction known as cement hydration during the early stage of the setting process. This is helpful in reducing the effects of high temperatures, which can speed up the setting process and prevent concrete from curing properly. They are usually calcium chloride, sulfate-based or organic amine and come in different concentrations to achieve the desired result.

These foam generators are used for total flooding application in areas like basement, mines, tunnels, cable ducts and warehouses. They are easy to operate and come with a portable design. They also have a convenient footswitch/pedal. This makes the machine easy to use.
These foam concrete generators work by mixing water and air together to create a foamy mixture that can be combined with cement and aggregate. The resulting mixture can be poured into molds or used to fill in voids. The process is similar to the way traditional concrete is made, but the addition of air means that the foam is lighter and less likely to settle.
A foam generator price is a great option for anyone who wants to do some concrete work around their home. This device can help them save time and money by making the job go faster and more smoothly. However, there are some important things to keep in mind when using a foam concrete generator.
First, it's important to make sure that the generator and foam concentrate are compatible with each other. This will ensure that the system will function correctly. Then, it's important to choose a suitable proportioning system and foam storage tank. It's also important to have a good supply of foaming chemicals on hand to make sure that the generator is always working at full capacity.
Form release agent, also known as concrete form release oil, is sprayed or brushed on molds and forms to prevent concrete from sticking as it cures. The type of form release agent you use depends on the type of mold rubber you're using as well as the makeup of your concrete admixture. A silicone rubber mold will release concrete easily, but over time it may degrade and lose detail. A urethane rubber mold, however, will bond with a concrete form release agent and stain it.
Suitable commercial form release agents are available for wood, metal and plastic forms. Oils such as straight refined, pale, paraffin-base mineral oil and oil-phased emulsions are satisfactory on wood; a petroleum jelly thinned with kerosene is good for plastic foam forms and plastic form liners. Release agents for steel are typically rust inhibitors. Concrete casters often try to make their own satisfactory release agents, but these concoctions can damage the mold and stain the concrete castings.
Foam concrete is an alternative to traditional concrete. It is a cement mixture that contains air bubbles that make it lightweight and more malleable than regular concrete. It is a good choice for a variety of applications, including filling holes and voids, repairing foundations and floors, and building walls. It is also useful for backfilling voids in pipes and sewer systems, culverts, and road trenches. It is easy to work with and requires minimal maintenance, making it a cost-effective alternative to traditional concrete. It is also fire-resistant and has good insulation properties.
The key ingredients in a foam concrete mix are water, a foaming agent, and cement. The mix is usually a typical mortar or concrete mix, though there are some that use pulverized fuel ash and ground granulated blast furnace slag in place of standard Portland cement. In order to get the best results, the cement should be thoroughly mixed with the foaming agent and water in a large container or tank, and then pumped into the desired location through a hose.
Once the water and foaming agent have been mixed together, compressed air is then forced through a lance that creates stiff white foam. This is then poured into the desired location and allowed to set. The result is a strong, durable concrete that weighs less than half as much as the same amount of conventional concrete.
A concrete foam generator for sale is an excellent way to make this construction material at home. The ingredients are available at most hardware and home improvement stores. When using this system, it is important to wear protective eyewear and gloves when handling the ingredients to ensure that you do not inhale the resulting fumes. It is also a good idea to have a large kitchen scale on hand so that you can accurately weigh the finished product.
