Study on Rubber Particles Modified Concrete

After rubber particles are incorporated into ordinary cement concrete, properties of concrete are changed. Specifically, by comparison with concrete without rubber particles, it reduces that the collapsed slump, apparent density, cubic compressive strength, splitting tensile strength and elastic modulus of rubber particles modified concrete. And when less than 50% of sand is replaced by rubber particles, rubber modified concrete can meet requirements of workability. Besides, its self-weight decreases, which is favorable for its structure to resist earthquakes.
