Superplasticizers in Concrete - Building Research

Superplasticizers are the improved chemical admixtures over Plasticizers with highly effective Plasticizing effects on wet concrete. Superplasticizers result in substantial enhancement in workability at a given water-cement ratio. For a constant workability, reduction of water content up to 30% may be achieved by the use of Superplasticizers.

Effect of Superplasticizers on Workability of Fresh Concrete

Jul 17,  · Effect of Superplasticizers on Workability of Fresh Concrete. 1.Type of Superplasticizers. It is a well-established fact that the average molecular weight of the plasticizer is of primary importance for its efficiency as a plasticizer in concrete. The higher the molecular weight, the higher is the efficiency.
