Abstract

The invention discloses environment-friendly water-permeable concrete for highway engineering. The environment-friendly water-permeable concrete is prepared from cement, palm ash, coarse aggregate, porous fine aggregate, fiber enhancer, micro silica powder and water. The invention also discloses a preparation method of the concrete. Compared with the prior art, the palm ash which is obtained afterpalm shells are burnt up, renewable polyethylene fibers and renewable polypropylene fibers are adopted as the raw materials for reinforcement of the concrete, waste is turned into treasure, the resources are utilized reasonably, and therefore the concrete has a significant meaning on environmental protection work. Additionally, the environment-friendly water-permeable concrete for highway engineering can improve the water-permeable performance remarkably when ensuring the pressure resistance and can also meet construction demands for highways.

Description

technical field [0001] The invention relates to a permeable concrete, in particular to an environment-friendly permeable concrete for road engineering. Background technique [0002] permeable concrete [0003] As a new type of pavement paving material with high permeability, permeable concrete has good ecological and environmental benefits. Due to the continuous expansion of modern cities, large areas of forests, grasslands and cultivated land have been destroyed, and the original virtuous cycle of biological ecosystems has been seriously damaged, and the pavement of large areas of impermeable and airtight traditional concrete water-blocking pavement materials , causing great pressure on the virtuous cycle of the urban ecological environment. The increasingly serious urban "heat island effect" has a serious impact on the exchange of water, air and heat in the city. Due to the dense urban buildings, the asphalt pavement and concrete cement pavement absorb a lot of heat duri...
