摘要
使M10等级的混合砂浆试块经历600℃高温,采用自然冷却和喷水冷却方式后进行了成分分析,并对不同温度不同冷却方式后黏土砖的强度进行了试验.研究表明:喷水冷却后砂浆成分中有CaCO3生成,强度有所提高;黏土砖在600℃以上高温后强度会有一定程度的下降.
Analysis was carried out on the components of composite mortar samples（M10）post 600 ℃and then under natural and water-jet cooling,and test on the strength of clay brick under different temperatures and cooling methods.The results revealed that CaCO3 was generated in mortar composition and the strength of mortar somewhat improved,while that of clay brick reduced to some extent after high temperatures of above 600 ℃.
