Product Description

Expansion And Shrinkage Reducing Agent:CSA Expansive Agent

CSA 112 is high-effective Expansion Agent manufactured from natural anhydrite and a special clinker which consists essentially of calcium sulphoaluminate and CaO. When it mixes in the proper proportion with ordinary cement, mortar or concrete can achieve certain shrinkage compensation or expansion at the early stage of hydration.

CSA 112 provides low alkali content, high effective expansion performance for concrete or mortar. The normal addition of CSA 112 is 6~8% by the weight of ordinary cement, which is much lower dosage than traditional expansion agent such as UEA and CEA (normally 10~12% necessary) to achieve the same shrinkage control.
