Abstract
1336772 Cement ONODA CEMENT CO Ltd 29 Dec 1971 [28 Dec 1970] 60309/71 Heading C1H Rapid hardening Portland cement containing 11CaO.7Al 2 O 3 .Ca Halogen 2 is obtained by adding at least one of CaSO 4 , CaSO 3 , CaS to raw materials of an aluminous material, a calcareous one, a siliceous one, an iron source and a halogen source, and burning in an oxidizing atmosphere. Preferably, the compound ranges from 0À5 to 4À5%, the calcareous material is a blend of 60 + % quicklime and 40 - % limestone; and the temperature is from 1265‹- 1400‹ C.
