【摘要】 介绍了采用直径45mm和70mm小芯样横劈法对遭受高温后混凝土抗压强度进行检测的试验研究．采用数理统计的方法给出了两种直径小芯样的测强方程和回归曲线，并对两者的关系进行了分析．更多还原

【Abstract】 An experimental research on the test of the compressive strength of the heated concrte with small dlameter cores of 45 mm and 70 mm by tranverse cutting method is introduced. By means of mathematical statistics, the test strength curves and regression equations of both small diameter cores are given.更多还原
