Abstract
In the present investigation, the primary hydration process of the cement concrete was studied by means of measuring the temperature of the core portion of the neat cement specimen. According to the above results, we considered the influence of the temperature on the set and the hardening of the cement concrete. The results of the present investigation have been interpreted as showing that the set and the hardening of the cement concrete are especially dependent on the curing temperature, among the temperature of cement, the mixing temperature and the curing temperature, and are impeded, when the mixing temperature or the temperature during the soculled dormant period of the cement hydration is higher.
