中文摘要	通过进行沙漠砂替代率不同沙漠砂混凝土高温后轴心抗压强度和静力受压弹性模量测定试验,分析温度和沙漠砂替代率对高温后静力受压弹性模量和轴心抗压强度的影响,建立高温后静力受压弹性模量和轴心抗压强度与温度、沙漠砂替代率之间回归模型。研究表明:沙漠砂混凝土高温后静力受压弹性模量和轴心抗压强度随温度升高逐渐减少。随沙漠砂替代率增加,沙漠砂混凝土高温后静力受压弹性模量和轴心抗压强度呈先上升后降低趋势。沙漠砂替代率40%时,高温后静力受压弹性模量和轴心抗压强度达到最大。
英文摘要	Axial compressive strength and elastic modulus experiments of desert sand concrete with different desert sand replacement ratios after high temperatures were carried out. The influences of desert sand replacement ratio and high temperature on the elastic modulus and axial compressive strength of desert sand concrete were analyzed. The axial compressive strength and elastic modulus regression model of desert sand concrete after high temperature were established. Experimental results show that the axial compressive strength and elastic modulus of desert sand concrete decreased gradually with temperature. The elastic modulus and axial compressive strength of desert sand concrete increase firstly,and then decline with desert sand replacement ratio. When desert sand replacement ratio amount to 40%,the elastic modulus and axial compressive strength of desert sand concrete reache the maximum value.
