Shenzhen Chenggong Trade Co.,Ltd. is supplying marine cements:
1. Sea Resistant Cement;
2. Sulfate Resistant Portland Cement(SRC).
1. Sea Resistant Cement:
Sea Resistance Cement has good and high resistance corrosion and high early strength. Sea Resistance Cement can for long resistance the corrosion of SO42-, Mg2+ or Cl- with the consistence 30000mg/L.
It has more better the character of resistance corrosion than High Sulfate Resistance Cement.
Its compressive strength at 1day can reach 60% of compressive strength at 28day.
Sea Resistance Cement is used widely in the resistance corrosion construction for example seaport, salt field, ridge and culvert of railway, shotcrete in tunnel, especial for the construction near sea.
2. Sulfate Resistant Portland Cement(SRC):
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(PMSRC) and 8000mg/L(PHSRC).
SRC is used in concrete engineering of harbor, water conservancy, underground, tunnel, drainage pipe, diversion works, road and bridge foundation, etc.
