RAPID HARDENING CEMENT COMPOSITION HAVING HIGH STRENGTH PROPERTIES

摘要

The cement is produced from compositions which contain 20 wt.% to 70 wt.% a calcium alumino sulfate(3CaO.3Al2O3.CaSO4), 15 wt.% to 60 wt.% a dicalcium silicate(2CaO.SiO2), a calcium alumino ferrite(6CaO.2Al2O3. Fe2O3) and clinker containing calcium sulfate(CaSO4) which is not bonded after clinker firing reaction, immicsible anhydrous gypsum, calcium hydroxide[Ca(OH)2 , fatty acid, oxycarbon acid, nitrogen-containing calcium salts. The accelated curring cement compositions according to this invention improve workability in a field of construction and temperature dependence, and can be used for concrete structure.
