Abstract
In the present investigation, the proctor penetration resistance of the concrete was studied by the following method of ASTM C 403. According to the above results, we considered the influnece of temperature on the setting and the hardening of cement concrete. The results of the preesnnt investigation have been interpreted as showing that the setting and the hardening of the cenent concrete are especially dependent on the curing temperature, among the temperature of making materials, the mixing temperature and the curing temperature, and impeded, when the mixing temperature or the temperature during the soculled dormant period of the cement hydration is higher.
