Abstract:The abrasion resistance of cement concrete containing scrap rubber particles by use of the test method specified in Chinese Test Method of Cement and Concrete for Highway Engineering JTGE30-2005 was researched in this paper .The test results showed that rubberized concrete had higher abrasion resistance compared with ordinary concrete, and its abrasion resistance had no inevitable relation with compressive strength. The abrasion resistance of rubberized concrete was reduced along with the increasing of water-cement ratio; the abrasion loss per unit area of rubberized concrete with water-cement ratio of 0.42 was decreased by 27% and 100% respectively compared with the rubberized concrete with water-cement ratio of 0.54 and 0.66. Along with the addition of rubber powder, the abrasion resistance of concrete was im-proved first and then reduced; when the content of rubber powder was more than 10kg/m3, the abrasion resistance of concrete would be reduced. Among the three different rubber powder with particle size of 80-mesh, 100-mesh and 120-mesh respectively, the concrete containing 100-mesh rubber powder had the best abrasion resistance, with abrasion loss per unit area de-creased by 39% and 4% respectively compared with the concrete containing 80-mesh and 120-mesh rubber powder.
