Abstract

A hydraulic cement is made by mixing and grinding together a finely ground clinker material containing tricalcium silicate, e.g. Portland cement, and carbonate of lime which has been artificially dried and contains less than .5 per cent of moisture. The carbonate is preferably ground to pass an 8-mesh sieve and so to be relatively coarse as compared with the clinker. The proportion of dry carbonate is preferably 8 parts of carbonate to 1 of free calcium oxide in the clinker. In an example limestone or other calcium carbonate is crushed to pass a one-inch mesh, dried so that not more than .5 per cent of moisture remains, and ground to pass an 8-mesh sieve. The ground dry carbonate is then mixed with clinker of a fineness to have not more than 1 per cent residue on a 76 mesh sieve and not more than 10 per cent on a 180 mesh sieve. The mixture is then ground until the whole passes through a 50-mesh sieve. Specifications 345,103 and 385,664 are referred to.
