A Study on the Properties of Materials Affecting the Strength of Concrete in Summer

The aim of this study is to accurately show the cause of repeated concrete strength decrease in summer and to help establish appropriate countermeasures. The evaluation results of seasonal cement (n=16) conducted jointly by SSANGYONG-clients from 2019 to 2022 were analyzed. As a result, it was confirmed that the chemical compositions, physical properties, and concrete performance of the seasonal cement were all at the same level. Through the evaluation of each concrete manufacturing condition considering the temperature conditions, the cause of the decreasing strength in summer was estimated and the improvement plans were reviewed.
