Abstract

Hydraulic cements are improved by admixing therewith organic hydroxy acids and/or salts or substitution products thereof such as esters, ethers and lactones. Acids specified include tartaric, citric, saccharic. They may be dissolved in the gauging water or added to the ground cement or to ground clinker to replace the usual setting regulators, and have a retarding effect. Accelerators and other substances including alkali permanganates, chromates, bichromates, chlorates, other hydraulic cements such as aluminous cement, alkali phosphates, compounds of sesquioxide metals and fluorine or oxalic acid, e.g. potassium - aluminium fluoride, aluminium oxalate, potassium-iron oxalate, and mixtures of alkali aluminate and alkali carbonate, may also be added. In examples (1) a Portland cement, sand and gravel mix is gauged with a 0.18 per cent solution of saccharic acid; (2) tartaric acid and aluminous cement, are added to a mix of Portland cement, sand and gravel; (3) a solution containing potassium carbonate, potassium aluminate, potassium - aluminium fluoride, tartar, and Weldon mud is added to a cement or mortar mix. Specification 379,320 is referred to.
