CSA expansive agent is a special expansive additives,which is also called polar bear csa in chinese construction market.CSA expansion agent has similar properties to denka csa *0# in expansive ratio,and has a good expansive compensation in preventing from cracking.
Advantages:
1.expansive compensation,with expansion it possessed,csa expansive agent can provent concrete from cracking and improve the quality of construction.
2.low alkali(R*0<=0.3%).It is obtained by grinding the mixture which consist of main binder material with anhydrous calcium sulphoaluminate and calcium oxide,suitable gypsum,not contain natural or baken alumstone,which is the best csa expansive agent to GRC products.
3.high efficicent expansive ratio.Low dosage about 6~8% to ordinary cement,which is lower than other expansive agent to gain the same effect in china.Therefore,it can reduce the cost of concrete construction in a way.
4.the same properties to Denka CSA *0# ,and have the similar application to it as well.
  Rapid hardening,fast set in repair project even in winter;
  Sulphate resistance,widely applied to marine construction;
  Shrinkage compensation,preventing  the concrete mixture from cracking after the process of retraining;
  Short time expansive period,it won't obvious expansion after *4 days later,which has no impact on the  later strength of commercial concrete.
