Abstract

The invention discloses spongy pervious concrete as well as a preparation method and application thereof, aggregate, cement, an adhesive and an additive are used as main raw materials, and through proper raw material proportioning, the types and dosages of the adhesive and the additive (water reducing agent) suitable for the spongy pervious concrete are preferably selected, so that the spongy pervious concrete is prepared. The pervious concrete has excellent decontamination capability, compressive strength and water permeability coefficient, can meet various engineering requirements on water permeability of concrete, and is beneficial to maintaining ecological balance and realizing sustainable development. And in addition, the manufacturing process is simple, the material source is wide, the method is suitable for large-scale production, on-site pouring and factory prefabrication can be achieved, and the market application and popularization value is extremely high.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to a sponge permeable concrete and its preparation method and application. Background technique [0002] As my country's urbanization rate increases year by year, the resulting large-scale urban expansion has led to over-exploitation of hydrological resources, a rapid increase in the proportion of dense pads, an increase in the coefficient of flood peak runoff, and the intensification of urban flood disasters, resulting in losses. At the same time, with the increase of traffic volume, road surface runoff pollution has become a problem that cannot be ignored. Traditional dense roads, due to their impervious characteristics, when rainfall occurs, rainwater collects in a short period of time, resulting in a rapid increase in short-term runoff and a large instantaneous flow rate, which also enhances the scour effect, making A large amount of pollutants accumulated on road surfaces on ...
