| 摘 要： | 为了探讨不同基准混凝土强度(C60,C40和C20)下,橡胶粉体积取代率和橡胶粉粒径对混凝土力学性能的影响,采用混凝土常规力学性能试验方法进行了橡胶混凝土和易性、抗压强度以及弹性模量试验。试验结果表明:橡胶混凝土立方体抗压强度、坍落度和弹性模量均随体积取代率的增加、橡胶粉粒径的增大而降低;橡胶粉体积取代率与强度降低系数之间存在较好的线性关系,回归分析的橡胶混凝土抗压强度方程形式简单,具有较理想的精度。

| Abstract: | In order to investigate the influence of rubber replacing ratio and rubber particle size of crumb rubber concrete with a compressive cube strength at 28 days of approximately 60MPa, 40MPa and 20MPa, the regular concrete testing methods were carried out on compressive strength, slump and Young"s modulus of rubber concrete. The test results showed that compressive cube strength, slump and Young"s modulus all decrease with the increase of rubber replacing ratio, and with the increase of rubber particle size. Based on regression analysis of the experimental data, a good linear relationship between rubber replacing ratio and strength reduction coefficient was found, and a compressive cube strength equation of rubber concrete at 28 days were proposed. The formula is simple, and the calculated results show good agreements with the experimental results. |
