Witton Cement Group Co., Ltd. Share: special cement rapid hardening cement classification: also known as early strength cement, usually in one day or three days to determine the compressive strength of cement grade. Its mineral composition can be divided into: rapid hardening Portland cement, fast hard aluminate cement, rapid hardening cement and sulphoaluminate Fluoroaluminate rapid hardening cement. Its early strength can be divided into different growth rates: Shanxi special cement rapid hardening cement to three days to determine the compressive strength value label; express hard cement, compressive strength value is determined in hours label, rapid hardening cement that Fluoroaluminate belongs to express hard cement. Witton Cement Group Co., Ltd. Share: classification of special cement sulphate resisting cement: sulfate corrosion of cement having a higher ability to resist. According to the mineral composition of cement can be divided into sulphate resisting portland cement, slag cement and belite strontium aluminate cement. Sulphate resistant cement according to the size of the special cement erosion model, can be divided into high sulphate resisting cement and sulphate resisting cement. Sulphate resisting Portland cement is the main varieties of sulphate resisting cement, Portland cement clinker by a specific mineral composition of Witton special cement, gypsum mixed with the right amount of ground together. Chinese standards: sulphate resisting Portland cement clinker, tricalcium silicate content of not more than 50%; tricalcium aluminate is not more than 5%; tricalcium aluminate, calcium and iron and aluminum four acid content of not more than 22%; free lime content shall not exceed 1.0%; magnesium content of not more than 4.5%; and sulfur trioxide cement content shall not exceed 2.5%; cement sulphate resistance index, which shall not be less than 0.8 Fb corrosion factor. Sulphate resisting cement applied to sulfate attack as well as by freeze-thaw and wet action harbor engineering, hydraulic engineering and underground engineering.
