Rapid-setting High-strength Calcium Sulfoaluminate Cement(CSA Cement)
Shenzhen Chenggong Trade Co., Ltd. supply high-strength rapid-setting low-alkali Calcium Sulphoaluminate Cement(also named CSA Cement,CSA Binder,SAC) for making GRC products.
CSA Cement has excellent performance of fast hardening, impermeability, low alkali, frost and corrosion resistance, etc.
CSA Cement is special fit for making GRC(glassfibre reinforce cement) board products. Moreover, it is widely used in making concrete with performance of impermeability, frost and sulfates corrosion resistance, precast component, pole, pipe and manmade marble goods.
Main mineral components in CSA Cement are Anhydrous Calcium Sulphoaluminate (4CaO?Al2O3嵩aSO4), Dicalcium Silicate (2CaO惹iO2), Gypsum (CaSO4?H2O). The Lime in SAC is bonded, not Free Lime.
CSA Cement has high early strength. Its performance of fast hardening, impermeability, frost and corrosion resistance is more excellent than those of Portland Cement. It has a remarkable effect on restraining alkali aggregate reaction. Its alkali is lower. PH value is only 10.5-11.
CSA Cement is widely used in making concrete with performance of impermeability, frost and sulfates corrosion resistance, precast component, glass fibre reinforced cement product, pole, pipe and artificial marble. With excellent quality, desirable performance and competitive price our SAC has been using in many large building engineering such as sea wall, expressway, airport runway, bridge.
