Early hydration of tricalcium silicate
WebCalculation of the dissolution rate of tricalcium silicate in several electrolyte compositions 1. Introduction. The hydration of tricalcium silicate (C. 3. S) proceeds through a the dissolution-precipitation process as explained a long time ago by H. Le Chatelier (1). The driving force of hydration is the difference in solubility between C. 3 WebJan 1, 2010 · Abstract. The seeding effect of finely dispersed calcium silicate hydrate (C-S-H) particles on tricalcium silicate hydration and on cement was investigated. An extremely small amount of C-S-H nuclei (0.3%) significantly increases the degree of hydration of both by promoting the growth of C-S-H clusters into the pore solution instead of around ...
