Cement and process for producing same

摘要

A cement having the following composition, parts by weight: }alite 1 to 50 }belite 1 to 45 }calcium chloroaluminate 30 to 1 }highly-basic calcium }chlorosilicate 75 to 5 }calcium chloro-orthosilicate 55 to 5 }calcium chlorcalumoferrite 2 to 22. } The cement is made by mixing the following ingredients, in parts by weight, calcareous component (calculated for CaO) 34 to 44, silicaceous component (calculated for SiO2) 9.5 to 17, aluminous component (calculated for Al2O3) 1.6 to 14, ferrous component (calculated for Fe2O3) 0.8 to 5, calcium chloride (calculated for CaCl2) 8.0 to 23, firing the mixture at a temperature of 1,000 DEG to 1,200 DEG C., and then at a temperature of 1,200 DEG to 1,400 DEG C. The product is then cooled and ground.
