1. Fast setting
2. Rapid Hardening
3. High early strength and bonding
4. Shrinkage compensation
Due to above mentioned characters, the Caliucm Sulfoaluminate cements can be applied in the production of foamed concrete where rapid demoulding increaseds the productivity and profitability.
Use our Caliucm Sulfoaluminate cements (CSA cements), the density of the foamed concrete products can be lower than 300kg/m3.
The Calcium Sulfoaluminate Cements can part or 100% replace of the OPC.
