Fosroc is a leading manufacturer and wholesale supplier of superplasticizer admixtures for concrete. Its products are designed to improve the properties of concrete, including durability and permeability. They are used in a variety of applications, including high strength concrete, ready mix concrete and mortar. These admixtures are also used to control shrinkage cracking, increase workability, and reduce the water content in concrete.

Conplast SP337 is a chloride-free water-reducing additive for concrete. It works by dispersing cement particles in water. This allows for reduction in the water content of the concrete, which in turn reduces the water demand and the amount of labour. It can also increase the early strengths and ultimate strengths of the concrete.

The new generation super plasticizer Auramix 350 can be used to retard setting time and to increase the strength of the concrete. This admixture is based on a polycarboxylic ether polymer.

For optimum results, the rate of addition should be calculated by site trials. Generally, 0.5 to 1 litres of admixture per 100 kg of cement is recommended. However, this can be higher or lower depending on the type of mixture and the mixing conditions.

Another example of a wide range of products is SikaPlast 3390. This superplasticiser is designed to enhance the performance of mid-high-range concrete admixtures.

Similarly, the Polytancrete Ngt Super Plasticising Admixture is a good admixture for improving the strength and modifying the properties of fresh concrete. It can be used in high temperature conditions and for dense concrete.
