Abstract

Generally, according to rising of atmospheric temperature, a consistency of concrete decreases, and a slump property of concrete is changed to be large. Also, in the strength development of concrete, the strength development rate of long-term age(28day) in comparison to strength of early age(7day) and the absolute compressive strength decreases. Accordingly, in this study, experiments about quality evaluation of concrete utilizing Ordinary Portland Cement is carried out. As a result of experiments, there were a conspicuous change in slump of concrete due to temperature increase. In conclusion, the rising of atmospheric temperature was very important factor in affecting the quality fluctuation of hot weather concrete.
