Abstract
A hydraulic cement comprises a clinker derived from burning a mixture of calcareous, siliceous and argillaceous material (i.e. of the type of Portland cement) and ground to British Portland cement fineness standard in admixture with calcium carbonate ground to a fineness such as to leave no appreciable residue on a 76 mesh sieve, and preferably of a fineness not greater than that of the cement. The amount of calcium carbonate is selected so as to be about 7 1/2 or 8 times that of the calcium oxide set free during hydration of the clinker, although in certain cases, e.g. for plastering, the amount may be increased, the excess carbonate then acting as aggregate. To delay setting retarders such as potassium dichromate, boric acid, borax, or sodium or potassium or calcium sulphate may be added to the mixture. Aggregate such as sand, small stones, fibre, &c. may be added. In examples are specified: 100 parts of clinker containing 12 per cent of free lime and 88 parts of calcium carbonate, 100 parts ground Portland cement clinker and 62.4 parts of calcium carbonate, 100 parts clinker containing 10 per cent of free lime and 80 parts of calcium carbonate; 100 parts clinker containing 6 per cent of free lime and 44 parts calcium carbonate; and for plastering a mixture including about 85 per cent of the total of calcium carbonate. Specification 345,103 is referred to.
