Abstract

668,550. Cement slurries. EVERY, C. E. (Smidth & Co., Aktieselskab F. L.). Jan. 10, 1950 [Feb. 14, 1949], No. 4022/49. Class 22 The water content of a raw cement slurry is reduced by adding thereto one or more alkali metal phosphates. In addition, one or more of the carbonates and hydroxides of the alkali or alkaline earth metals may be included; also sulphite lye or sodium silicate individually or in combination. Specific additions are sodium and potassium meta phosphates, sodium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, sodium hexametaphosphate, sodium pyrophosphate, sodium carbonate, and calcium and sodium hydroxide. The total amount added is 0.2 per cent by weight. Lime slurries may also be similarly treated. According to the Provisional Specification the phosphate need not be present.
