High Efficiency CSA Expansive Agent is a special calcium sulphoaluminate cement additive. It has efficiency expansion ratio(about 6~8% to ordinary cement ).Its main efficient content is calcium sulphoaluminate and calcium oxide.
High efficiency CSA expansive agent is designed to mix with ordinary cement as concrete additive. It can minumize the dry shrinkage of concrete, and it can produces self-stress(0.2~0.7***) when restrained to prevent cracking as well as waterproofing.
High efficiency CSA expansive agent has gained the national invention patent. The patent No is 02116312.X.
Application:
The properties of expansion is similar to Denka CSA 20# and CSA Power Types or other types of expansion agent like UEA, CEA. And it can be added to concrete or mixed with ordinary cement in construction as below:
1. Railway, tunnel, crack and waterproof layer of the high-rise building.
2. Auto-waterproofing rigidity of surface, impermeability resistance mortar, wet resistance mortar ect.
3. Non-grouting mortar
ect.
