通过对三种不同橡胶掺量的混凝土试件进行高温试验，研究了橡胶混凝土经历不同高温作用后，试件表观变化现象、质量损失、抗压强度和劈裂抗拉强度，以及弹性模量的衰减规律。试验结果表明，高温作用后，橡胶集料改性混凝土的各项力学指标衰减随橡胶掺量的增加而增大，随受热温度的升高而增大，500℃高温作用后出现陡降。

Through the high-temperature tests on concrete specimens of three different amounts of rubber admixture,it studied after the different high-temperature effects on rubber concrete,the apparent change of specimens,the mass loss,the compressive strength, the splitting tensile strength and the reduction regularity of elasticity modulus. The test findings show that after the high-temperature in-fluence,the mechanics indexes of the specimen reduce with the increase of the rubber crumb and increase with the increase of the heat-ing temperature. After 500 ℃,the specimen strength appears a steep drop.
