中文摘要	为了研究沙漠砂混凝土高温后劈裂抗拉性能,进行了628个100 mm100 mm100 mm沙漠砂混凝土试件高温后劈裂抗拉强度试验,分析沙漠砂替代率和受火温度对沙漠砂混凝土高温后劈裂抗拉强度的影响,建立沙漠砂混凝土高温后劈裂抗拉强度劣化模型。研究表明:沙漠砂混凝土劈裂抗拉强度随着温度升高呈现先增大后减小趋势;随着沙漠砂替代率增加,高温后沙漠砂混凝土劈裂抗拉强度亦呈现先增大后减小趋势,沙漠砂替代率40%时,沙漠砂混凝土劈裂抗拉强度达到最大值。
英文摘要	In order to study the splitting tensile properties of desert sand concrete,the splitting tensile strength experiments of 628 desert sand concrete specimens with the size of 100 mm 100 mm 100 mm were tested after being subjected to different temperatures. The influences of desert sand replacement rate and temperature on the splitting tensile strength of desert sand concrete were analyzed. The degradation models of splitting tensile strength of desert sand concrete after being subjected to high temperature were established. Experimental results showed that the splitting tensile strength of desert sand concrete increased firstly,and then declined with the temperature. At the same time,with the enhancement of desert sand replacement rate,the splitting tensile strength of desert sand concrete also increased firstly,and then declined. When desert sand replacement rate was equal to 40%,the splitting tensile strength of desert sand concrete reached the maximum value.
