Shenzhen Chenggong Building Materials Co., Ltd. (www.chngn.com) supplying Sulfate Resistant Portland Cement(SRC), including High Sulfate Resistant Cement(HSRC) and Moderate Sulfate Resistant Cement (MSRC).
SRC has excellent characteristics of sulfate corrosion resistant. Generally it can effectively prevent pure sulfate corrosion when the concentration of sulfuric acid radical ion is not more than 2500mg/L(MSRC) and 8000mg/L(HSRC).
SRC is used in concrete engineering of harbor, water conservancy, underground, tunnel, drainage pipe, diversion works, road and bridge foundation, etc.
