Product Description

Shenzhen Chenggong Building Materials Co., Ltd. (www.chngn.com) supplying 82.5 high-strength rapid-setting CSA Cement, also named Calcium Sulfoaluminate Cement, R-SAC.

Grade: 82.5.

82.5 CSA Cement has excellent performance of fast hardening, impermeability, low alkali, frost and corrosion resistance, etc.

Main mineral components in CSA Cement are Anhydrous Calcium Sulphoaluminate (4CaO·3Al2O3·CaSO4), Dicalcium Silicate (2CaO·SiO2), Gypsum (CaSO4·2H2O). The Lime in CSA Cement is bonded, not Free Lime.

82.5 CSA Cement has high early strength. Its performance of fast hardening, low-alkali, impermeability, frost and corrosion resistance is more excellent than those of Portland Cement. It has a remarkable effect on restraining alkali aggregate reaction.

82.5 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.

82.5 CSA Cement can be used in making foamed cement boards and foamed slag concrete products.

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.

If to be used together with type SAC-1 Rapid-setting Accelerator, 82.5 CSA cement can get more rapid setting and fast hardening and more rapid demould.
