胶粒混凝土弹性模量是胶粒混凝土的重要性能参数。采用三因素、三水平的正交试验设计方法对胶粒混凝土的配合比进行试验设计，探讨水胶比、胶粒掺量、胶粒粒径对胶粒混凝土弹性模量的影响，并与基准混凝土进行对比。试验结果表明：掺入胶粒的混凝土的弹性模量明显降低，约为基准混凝土弹性模量的60％～70％，且胶粒混凝土的弹性模量主要受胶粒掺量的影响，为其显著影响因素。每增加15％的胶粒掺量，混凝土的弹性模量约降低21．53％。采用多元回归的分析方法，建立了胶粒混凝土弹性模量与水胶比、胶粒掺量、胶粒粒径的经验公式。

The elastic modulus of rubber concrete is one of the important performance parameters of the concrete .In this paper ,three factors and three levels of orthogonal design method to mix concrete is designed to explore the water‐cement ratio ,rubber content , rubber particle size of the particles influence of elastic modulus of concrete The results showed that :the incorporation of rubber elas‐tic modulus of concrete decreased approximately 60% to 70% of the reference concrete ,and the modulus of elasticity of concrete is mainly affected by rubber particles content which is a significant impact factor .Each additional 15% of the rubber content ,lower modulus of elasticity of concrete is about 21 .53% .By using multiple regression analysis ,the empirical formula rubber elastic modulus of concrete and cement ratio ,rubber content ,particle size of the particles are established .
