Lactate activated cement and activator compositions
The present invention relates to a lactate activated cement and activator compositions. Cementitious compositions in which the cementitious properties of fly ash are carefully controlled are described. The cementitious compositions may be substantially free harsh acids and bases such as citric acids (PRG pH 2.2) and alkali metal activators including alkali hydroxides (PRG pH 12-14) and metal carbonates (PRG pH 11.6). The use of these harsh chemicals creates acid base reactions during use of the products. Instead of these harsh chemicals, a lactic acid salt based activator is be used as a reaction accelerator. Boric compounds may be used as a retarder in the compositions.
