Due to the increasingly serious environmental problems presented by waste tires, the feasibility of using elastic and flexible tire-rubber particles as aggregate in concrete is investigated in this study. Tire-rubber particles is composed of tire chips, crumb rubber, and a combination of tire chips and crumb rubber. Experimental work of Waste Rubber Particle Reinforced Mortar(WRPRM) have been conducted in the form of cube specimens [50mm x 50mm x 50mm], beam specimens [40mm x 40mm x 160mm] mixed with 0%, 5%, 10%, 15%, 20%, 25% of rubber particle. We executed test for compression strength test, bending strength test on 7 days, 14days, 28days and percentage of moisture content test on 28days after initial curing. In this study, We studied the initial strength of WRPRM. But, in order to understand the reinforcing effect of the rubber particles, we need to execute a test of Waste Rubber Particle Reinforced Concrete(WRPRC).
