Thermal Study of the Effect of Additives on the Hydration of Tricalcium Silicate

Abstract
The rate of paste hydration of 3CaO·SiO2(C3S) and the effects of additions of CaCl2, CdI2, and CrCl3, were studied by differential thermal analysis and thermogravimetry. X‐ray analyses were used to identify the synthesized C3S. The salts CaCl2, CdI2, and CrCl3, accelerated the hydration of C3S. The degree of hydration was estimated by the amount of Ca(OH)2, formed, as determined by TG.
