摘要：
All chemical admixtures added to concrete in order to improve the workability in fresh state and to improve its final properties, have a significant influence on the reaction kinetics of hydration. The knowledge of this effect is very important not only for the optimization of a cement mixture but even for the optimal placing of concrete process. Considering the fact the clinker minerals hydration is an intensive exothermic reaction, it is possible to control this process by means of intensity measurement of hydration heat development.
