ON THE STRENGTH DEVELOPMENT AND TIME FOR FORMWORK TO REMAIN IN PLACE OF CONCRETE EFFECTED WITH TYPES OF CEMENTS

This paper presents the results of experimental studies on the strength characteristics of concrete. Strength development of concrete is influenced by the types of cements and the curing temperature. Therefore, in this research, it is found that the temperature range for temperature compensated specified strength T of JASS 5 is proper, and the time for formwork to remain in place is proposed according to the types of cements. As for Young's modulus, correction factor for the types of cements should be considered to the AIJ expression of it.
