摘　　要：针对目前橡胶粉生产工艺多种多样,不同工艺生产的橡胶粉对混凝土性能影响不一的现象,采用助剂法、摩擦法和切削法3种工艺生产的6种橡胶粉,掺量20%等体积取代砂的条件下,研究了各种橡胶粉对混凝土性能的影响。研究结果表明,助剂法生产的40目橡胶粉混凝土的工作性能、抗压强度、劈裂强度最好,摩擦法生产的40目橡胶粉混凝土弯拉强度、柔性最好。Aiming at a variety of rubber powder production technologies at present,rubber powder of different production technologies has different effects on concrete properties, six kinds of rubber powders arc produced using three kinds of production technologies i.e. methods of additive,friction and cutting. The effect of various rubber powders on performance of concrete was researched under the condition of 20% content replacing the same volume of sand. The results show that 40 mesh rubber powder concrete produced by additive method has the best workability, compressive strength and splitting strength,and 40 mesh rubber powder concrete by friction method has the best flcxural strength and flexibility.
