Superplasticizers and plasticizers for concrete

Information on plasticizers and superplasticizers is included in Section 13.5. The following are the structures of some commercially used superplasticizers (chemical compositions of plasticizers are listed in Section 13.5)  

R= H or methyl M = metal acrylic acid-based polycarboxylate 

Superplasticizers were discovered in 1960s. The poly- 3-iiaphthalene sulfonates were the first to be introduced and the most widespread superplasticizers followed by polymelamine sulfonates. Organic polymers having carboxylic group are the most recent 

Outstanding property reduction of water required, improved slump resistance
