摘　　要：文中研究了含稻壳灰混凝土暴露于高温并迅速冷却后的残余抗压强度。将含稻壳灰混凝土置于不同温度下,采用自然风冷和喷雾水冷两种降温方式使混凝土试件冷却至室温,并以普通硅酸盐混凝土在相同条件下的变化做对比。结果表明,在经历不同高温和冷却方式降温后,含稻壳灰混凝土的残余抗压强度均高于普通混凝土的残余抗压强度。此外,与自然风冷相比,喷雾水冷的方式会降低混凝土的残余抗压强度。This paper studies the residual compressive strength of concrete containing rice husk ash after exposure to high temperature and rapid cooling. In the experiment, the concrete containing rice husk ash was placed at different temperatures, and the concrete specimens were cooled to room temperature by natural air cooling and spray water cooling, and compared with the changes of ordinary silicate concrete under the same conditions. The results show that the residual compressive strength of concrete containing rice husk ash is higher than that of ordinary concrete after experiencing different high temperatures and cooling methods. In addition, compared with natural air cooling, spray water cooling will reduce the residual compressive strength of concrete.
