How does superplasticizer work?

Superplasticizer is essentially a kind of building materials, in use will produce foam and bubble and other sol bubbles, and they have different characteristics and formation mechanism, is caused by ionic superplasticizer. After adding the superplasticizer to the concrete, the superplasticizer will be adsorbed on the surface of cement particles. Generally, about 80% of the superplasticizer …

Who Invented Superplasticizer?

The Japanese catalyst company Tsubaki Hengxiong invented the polycarboxylic acid water-reducing agent in the 1980s. Its molecular structure is no longer the same as the linear structure of the previous high-efficiency water-reducing agent. Comb-shaped molecular structure composed of chains and long polyoxyethylene side chains. Immediately afterwards, an ester-based carboxylate water-reducing agent obtained by copolymerization of …

why does adding superplasticizer improve flow?

Superplasticizers (SP’s), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with ca. 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and …
