  • Cement and process for producing same
    Patent number: 4119467
    Abstract: 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 SiO.sub.2) 9.5 to 17, aluminous component (calculated for Al.sub.2 O.sub.3) 1.6 to 14, ferrous component (calculated for Fe.sub.2 O.sub.3) 0.8 to 5, calcium chloride (calculated for CaCl.sub.2) 8.0 to 23, firing the mixture at a temperature of 1,000.degree. to 1,200.degree. C., and then at a temperature of 1,200.degree. to 1,400.degree. C. The product is then cooled and ground.
    Type: Grant
    Filed: May 17, 1977
    Date of Patent: October 10, 1978

  • Raw mixture for the production of cement
    Patent number: 4115138
    Abstract: A raw mixture for the production of cement consisting of calcareous, aluminous, silicaceous, ferrous, magnesium-containing components and calcium chloride; said components being contained in the raw mixture in the following proportions, per cent by weight:______________________________________ calcareous component (calculated for CaO) 30 to 42.3 silicaceous component (calculated for SiO.sub.2) 12.5 to 17.5 aluminous component (calculated for Al.sub.2 O.sub.3) 1.6 to 12.4 ferrous component (calculated for Fe.sub.2 O.sub.3) 0.6 to 4.4 magnesium-containing component (calculated for MgO) 1.5 to 8 calcium chloride 6 to 20 losses at calcination the balance. ______________________________________The above composition makes it possible to perform calcination of the raw mixture at substantially lower temperatures (within the range of from 1,000.degree. to 1,100.degree. C) and to obtain cement possessing a higher activity.
