167,138. Winkler, K. July 26, 1920, [Convention date]. Concretes &c.-Cements, mortars, concretes, &c. are rendered waterproof, adhesive, and quicksetting by being gauged with a calcium chloride solution of about 23‹ BÚ. Preferably from to 3 per cent of calcium nitrate, strontium nitrate, magnesium nitrate, manganese dioxide, manganese oxide, barium peroxide, chromic oxide, oxide of antimony, butter of antimony, manganese borate, or sugar, or a mixture of these substances, is also added to the cement. The action of the metallic chloride is further intensified if from 2 to 7 per cent of coal cinders, calcspar, feldspar, bauxite, heavy spar, or fluor-spar is incorporated with it during its manufacture from the corresponding carbonate or oxide. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of at least one metallic chloride soluble in water, preferably dissolved in the gauging water. This subjectmatter does not appear in the Specification as accepted.
