1. Concrete accelerator is a kind of surface active material, added to concrete, cement particles play a diffusion effect, the cement condensate free water released, so as to keep the concrete performance unchanged and significantly reduce water consumption, reduce water-cement ratio, improve workability, increase fluidity, save cement. The varieties of water reducing agent are lignin series, nano sulfonate series, water soluble dense amine resin class, sugar dense class.
2. Concrete accelerator can make mortar, concrete produce a large number of fine uniform distribution of closed bubbles, can improve the workability of concrete, improve the impermeability, frost resistance and durability, entraining agent varieties have alkyl sodium sulfonate, soap, OP emulsifier, 8012 and so on.
3. Concrete accelerator is the admixture of concrete or mortar due to chemical reaction and expansion, the main role is to compensate the shrinkage of concrete. Expansion agent products are calcium aluminate sulfur, gypsum, iron powder, lime, alum stone and so on.
