摘　　要：以未处理、清水清洗、NaOH溶液清洗、CCl4溶液清洗等不同橡胶颗粒预处理方式为主要影响因素,通过对51个橡胶混凝土试件的试验研究,得出了不同预处理方式对不同橡胶粒径和掺量的橡胶混凝土工作性能和抗压强度的影响规律.结果表明:采用清水、NaOH溶液、CCl4溶液等预处理方式的橡胶混凝土工作性能和抗压强度均有不同程度提高,且橡胶颗粒越大、掺量越小预处理对橡胶混凝土工作性能和抗压强度的提高越明显.Different pretreatments for rubber particles are taken as the main influencing factors, such as untreated, treating with clean water, cleaning with NaOH solution, and cleaning with CC14, etc. Through the experimental study of 51 rubber concrete specimens, the influence rules of different pretreatments on the work performance and compressive strength of rubber concrete with different rubber particle size and content are obtained. The results show that： the work performance and compressive strength of rubber concrete are improved in varying degrees by using the pretreatments of water, NaOH solution, and CC14 solution; the larger the rubber particles and the smaller the content is, the more obvious the improvements of the work performance and compressive strength of rubber concrete by pretreatment are.
