抄録

The effect of kind of structural members and construction seasons on distribution of compressive strength and strength development of concrete in structures made with high-strength concrete were investigated based on many data from full-scale experiments which were carried out for past about 15 years. The results are summarized as follows: (1) The strength development of concrete in structure from 28 days to 91 days in summer is smaller than that in winter. (2) The ratio of compressive strength of 91 days core specimen to 28 days standard-cured specimens is nearly equal in columns and column-beams joints, but about 96% in beams and about 90% in slabs.
