摘要
通过大量的工程案例分析 ,考虑了不同温度、不同静置时间、不同冷却方式及不同养护条件等因素 ,进行混凝土材料性能主要是抗压强度与温度及静置时间的试验研究 。
The effects of high temperature on compressive strength of concrete are studied. An electronic oven of the type of KJX?45?9 is used in the test. Some specimens are cooled down in nature circumstance after high temperature; others are cured in standard room. The behaviors of concrete under different conditions are discussed in details. It includes the temperature, stock?still time, cooling modes, and curing circumstances. At last,a formula for the compressive strength of concrete is proposed in the paper.
