Abstract
A cement having a rapid initial set, e.g. within 12 seconds, and a sufficiently slow hardening speed to avoid the formation of cracks by the evolved heat, comprises a mixture of aluminous cement and Portland cement or other calcium silicate cement free from gypsum or other retarding agent. The cement may be made by mixing the two kinds of clinkers, e.g. in pro portion from 1 to 3 to 3 to 1, and grinding. The cement is specially intended for the repair of walls and masonry through which water is seeping, the cement being applied by a cement gun to the moist surface of the structure remote from the water pressure. It may also be utilized in building construction, layers of the cement being applied by a gun or otherwise. Reference has been directed by the Comptroller to Specifications 18345/08, [Class 70], and 231,867, [Class 22].
