Impact of Temperature Rising Inhibitor on hydration kinetics of cement paste and its mechanism

This study examines the effect of Temperature Rising Inhibitor (TRI) on Portland cement hydration process and analyzes the mechanism. The investigation of the impact of TRI on cement dissolution, C-S-H nucleation and growth process shows that TRI has little influence on the dissolution kinetics of cement and crystal-solution interfacial energy of C-S-H. In contrast, the modification of C-S-H grain size in solution and the C-S-H growth rate in cement suspensions are observed. Experiments involving TRI and synthesized C-S-H confirm that TRI will preferentially adsorb on the C-S-H surface and inhibit growth of C-S-H.
