The Mechanical Properties of Concrete Mixed with Plastic Coated Crumb Rubber

Abstract

This research studied the properties of concrete which can be used to replace coarse aggregate (by rubber pellets No.6 from old tire scraps coated with LDPE plastic with a proportion (ratio) of rubber pellets to plastic pellets at 50/100 and 70/100, respectively.) By replacing the coarse aggregate at 10, 20 and 30 percent, respectively, the mechanical properties of engineering in terms of compressive strength and flexural strength can be improved. The results show that although the compressive strength and flexural strength of concrete rubber is capable of being decreased, the flexibility increased. It was also found that the compressive strength and flexural strength of concrete at 10 percent is higher than at 20 and 30 percent.
