polycarboxylic acid admixture superplasticizer in cement

Regarding the role played by the incorporation of water-reducing agents in concrete,  A. If the mixing water consumption is not reduced, the fluidity of the mix can be significantly improved B. When water is reduced without reducing cement, the strength of concrete can be increased C. If the water reduction is accompanied by an appropriate reduction in the amount of cement, the cement can be saved.  Commonly used concrete admixtures (admixtures mixed with chlorine salts should pay special attention to the corrosion of steel bars and concrete; Steam curing concrete and prestressed concrete, do not mix air entrainment agent and air entrainment water reducing agent)   (1) Water-reducing agent (with water-reducing enhancement)   The technical and economic effect of adding water reducing agent: improve strength, improve compactness, improve durability, improve fluidity, save cement Main varieties: ordinary water reducing agent lignosulfonates, such as lignosulfonates (wo…
