摘要
通过对普通混凝土耐火性能试验的初步探讨,表明普通混凝土具有一定的耐火能力,耐火性能受强度等级和试件尺寸等因素的影响,质量损失和强度损失随温度升高和时间延长呈现规律性变化。
Through the study on the fire resistant performance test of ordinary concrete,it shows that the ordinary concrete has the fire resistant capacity,and the fire-resistant performance is influenced by the intensity level and the specimen size,quality loss and strength loss changes regularly with increasing temperature and time extend.
