Abstract

The invention belongs to the technical field of concrete and particularly relates to a pervious concrete formula and a construction method. According to the formula, the pervious concrete is composed of, by weight, 260-440 parts of cement, 90-150 parts of second-class coal ash, 90-160 parts of slag powder, 1500-1650 parts of broken stone, water, a binding material, a lime concrete reinforcing agent, polycarboxylate superplasticizer, inorganic mineral oxide pigments and an oleoresin top facing agent, wherein the mixing ratio of water to lime is 0.25-0.40, and the mixing ratio of water to the binding material is 0.25-0.40. The binding material is a mixture of cement, second-class coal ash and slag powder with the mixing ratio of 3:1.5:1. The oleoresin top facing agent is acrylic resin.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a permeable concrete formula and a construction method. Background technique [0002] The permeable concrete pavement material is an environmentally friendly and ecological concrete material, which has water permeability and air permeability, and its basic composition materials are not essentially different from ordinary concrete materials. The difference is that ordinary concrete always finds ways to reduce the porosity to make it dense and achieve high strength and high durability, while permeable concrete uses a special material formula to meet the performance requirements of the road surface. At the same time, it can achieve Its porous and continuous structure makes it have good water permeability. When rainfall is concentrated, rainwater can infiltrate into the ground in time through the connected pores to achieve the purpose of rapid drainage and replenishment...
