摘要
主要介绍采用直径４５ｍｍ和７０ｍｍ小芯样抗压及横劈法对高温后混凝土抗压强度进行检测的试验研究。并用数理统计的方法对得到的测强方程和回归曲线进行了定量的分析。
This paper introduces an experimental research on the compressive strength of the heated concrete tested on the small cores of 45 mm and 70 mm in diameter by compression and transverse cutting methods.By means of mathematical statistics, the test strength equations and regression curves obtained are quantitatively analyzed.
