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.

Many waste rubber are produced every year, waste rubber is of good chemical and biological resistance. And it is hard to degrade in natural conditions. Therefore, it is extremely difficult to treat waste rubber. However，rubber particles made from waste tires are added into concrete. This can not only improve properties of concrete effectively but recycle a large number of waste tires.

Huijin developed the ammonia free denitration kiln tail sintering system to lower the Nox effectively and saving ammonia water by more than 60%. Huijin panted distribution measurement ammonia water injection system also can perfectly slove the unevenly distribution problems of ammonia water, The lower Nox energy saving rotary kiln burner will also help dealing with the Nox problems. Pls feel free to contact us for more information.
