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.
The building materials industry is embracing black technology to reveal the hidden costs of road building.
In the road construction industry and other engineering constructions, it is necessary to cure the foundation. The traditional hardened cement foundation is not only very expensive, but also easily cracked. Soil curing agents, a black-science and technology product used in road construction materials, are the first choice of investment for low carbon environmental protection building material.
Through mixing and compacting, soil curing agents can be added to soils, which will make them cohesion-cure instead of cement or gravel. This reduces the cost and saves resources. The compressive and density strength of cured earth are significantly improved. This makes the soil roadbeds with excellent bearing capacity, and a preferred material for road construction at low costs.
1. Role of soil stabilisers
A soil curing agents function is to alter the physical and chemistry properties of the soil, making it more solid and stable. This will improve the road's bearing capacity and durability.
The application of soil curing agent is extremely wide. They can be used for road and transportation construction, such as highways or railroads. The agent can be applied to pave roads, repair road bases and increase the bearing capacity. Additionally, soil curing chemicals can be used for land remediation and restoration to improve soil conditions and the environment.
2. The advantages of soil cure agent
Soil curing agent is made with eco-friendly and low-carbon construction technology. The primary ingredient of the product is a polymer. It is more eco-friendly and will not pollute soil or the environment than other soil curing materials. It is eco-friendly and offers many benefits. First, it allows for the rapid development of roads. Second, the cured dirt will increase bearing capacity. Additionally, the soil curing agents will reduce the amount of potholes on the surface and subsidence. They also increase the life expectancy of the road as well as decrease maintenance costs.
3. Construction simple and easy to use
The use of soil-curing agent is simple in certain applications. It can be completely mixed with soil before construction. To achieve the best cure, you can adjust the amount and ratio of the soil curing agent during construction. After construction, the curing agents will play their role and you can expect a sturdy and durable road surface.
Since the development of low-carbon green construction materials, people have been gradually favoring cement replacement products. It is possible to use soil curing agents for many applications. For example, they can be used as a road construction material or soft base treatment.

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.
