Abstract

The invention discloses pervious concrete and a construction method thereof. The pervious concrete comprises the following raw materials in percentage by weight: 13.1-15.9% of cement, 12.7-15.6% of river sand, 59.6-66.0% of stones, 3.7-3.9% of water and 4.5-5.0% of admixtures, wherein the admixtures comprise the following raw materials in percentage by weight: 45-50% of ultrafine mineral powder, 15-20% of heavy calcium carbonate, 15-20% of gypsum powder, 3-5% of polypropylene fiber, 5-10% of a polycarboxylate water reducing agent, 4.2-8.4% of adhesive powder and 2-5% of a pigment. The pervious concrete provided by the invention has relatively high water permeability, strength and durability; after the pervious concrete is applied to a practical engineering, the pervious concrete can greatly improve the problem of poor drainage of a hardened road surface, so that the development of the pervious concrete can be promoted.

Description

technical field [0001] The invention relates to a concrete pavement material and a construction method thereof. Background technique [0002] The surface of the modern city has been covered by reinforced concrete buildings and impermeable roads. Compared with natural soil pavement, ordinary concrete pavement lacks breathability, heat absorption and water permeability, which brings a series of environmental problems. At present, ordinary concrete has extremely poor water permeability, which puts great pressure on the drainage system of the road surface. The rainwater that cannot penetrate the ground can only be discharged into the river through the drainage system, which brings a great burden to urban rivers. [0003] Permeable concrete is a kind of concrete with continuous pores prepared through strict material research and optimization, and through a specific preparation process. Pervious concrete not only has a certain strength, but also has a certain water permeability....
