The hazards of wet cement are due to its caustic, abrasive, and drying properties. Wet concrete contacting the skin for a short period and then thoroughly washed off causes little irritation. But continuous contact between skin and wet concrete allows
Manufacturing Of Portland Cement Process And Materials
Apr 13, 2020 The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical
