摘　　要：针对橡胶颗粒混凝土的抗压强度和压缩变形量性能研究,利用正交设计试验法选取了橡胶颗粒种类、掺量、水灰比和砂率四个因素及其各自三个水平,对橡胶颗粒混凝土抗压强度和压缩变形量影响因素的主次顺序及最优配合比组合进行探讨。研究结果表明,水灰比和橡胶颗粒的掺量对橡胶颗粒混凝土抗压强度以及压缩变形量的影响均大于砂率和橡胶颗粒种类对其影响。In order to take a performance research on the compressive strength and compression deformation of rubber concrete,this essay utilizes orthogonal experimental design method to select the such four factors as rubber particle type,rubber particle dosage,water cement ratio and sand ratio as well as their three levels respectively,and discusses the primary and secondary order of the influence on the compressive strength and compression deformation of rubber concrete,and also choose the optimum of mix proportion.It shows that the water ratio and rubber particle dosage affect more than the sand ratio and rubber granule type to the rubber concrete.
