Abstract

In order to improve the plasticity of hydraulic binding-agents such as cement, lime, or plaster of Paris, there is added an organic substance which forms a soluble alkaline-earth metal complex salt. The substances are (a) amino acids having two carboxyl groups of the formula R.N(CH2COOH)2, R being hydrogen or an organic residue, e.g. nitrilo triacetic acid, ethylene diamine tetracetic acid, imino-diacetic acid, methylimino-diacetic acid, anthranil acid diacetic acid, uramil 7.7-diacetic acid or their alkali metal salts; (b) pyrocatechin disulphonic acid or its alkali metal salts; or (c) sodium citrate. Setting-regulators, such as alkaline earth or aluminium chlorides, aluminates, alkali hydroxides or carbonates, or waterglass, may be included. The substances may be introduced during manufacture of the binding-agent or may be added with any of the ingredients during mixing.
