| Abstract: | On the Influence of Admixtures on the Hydration of Tricalcium Silicate (Ca3SiO5) The influence of several compounds (alcohols, ketones, organic acids and the ir salts, cation exchange resin) on the hydration of tricalcium silicate was investigated by means of differential calorimetric analysis (DCA). The acceleration and retardation of this reaction found in these experiments are discussed on the basis of Ca(OH)2 solubility, the pH of the solution and the rate of conversion of a C? S? H rich in CaO into a C? S? H poor in CaO at the surface of the C3S grains. |
