Product Description

Shenzhen Chenggong Building Materials Co., Ltd. supplying rapid-setting high-early-strength Calcium Sulfoaluminate Cement,also named CSA Cement, SA Cement.

Grade: 42.5.

42.5 Calcium Sulfoaluminate Cement has excellent performance of fast hardening, impermeability, low alkali, frost and corrosion resistance, etc.
42.5 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 about 11.

CSA Cement is special fit for making GRC(glassfibre reinforce cement) 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, foamed cement boards, foamed concrete products, etc.
 

If to be used together with type SAC-1 Rapid-setting Accelerator, grade 42.5 CSA Cement can get more rapid setting and faster demoulding.

With excellent quality, desirable performance and competitive price our CSA Cement has been using in many large building engineering such as sea wall, expressway, airport runway, bridge.
