Waste polypropylene fiber rubber recycled concrete and preparation method thereof
The invention discloses waste polypropylene fiber rubber recycled concrete and a preparation method thereof. The waste polypropylene fiber rubber recycled concrete is prepared from the components in parts by weight: 1-10 parts of polypropylene fiber, 5-20 parts of a rubber powder, 0-1600 parts of a recycled coarse aggregate, 0-1600 parts of gravels, 300-500 parts of sand, 300-500 parts of cement, 150-300 parts of water, and 50-100 parts of an additive. The waste polypropylene fiber rubber recycled concrete can be applied in road construction, reduces road noise and vibration, increases the collision buffer distance between automobile tires and roads, and increases the elasticity and toughness of a concrete pavement. At the same time, the used polypropylene fiber and the used rubber powder are mostl.y polypropylene fiber clothing, discarded tires and the like, not only are the pollution of the wastes to the environment and the occupied cultivated land area reduced, but also the elasticity and toughness of the concrete can be improved, concrete pavement cracks generated due to temperature change are reduced, and thus the waste polypropylene fiber rubber recycled concrete is not only environmentally friendly but also has relatively high practical value during application.
