Pervious concrete

Abstract

The invention relates to pervious concrete. The pervious concrete is prepared from the following components in parts by weight: 106 parts of cement, 35 parts of limestone powder, 33-65 parts of aggregate, 12-24 parts of iron powder, 22-27 parts of macroporous resin, 4-9 parts of sodium sulfite powder, 10-30 parts of adhesive, 12-15 parts of reinforced fibers, 150-180 parts of cobblestones, 1-2 parts of a foaming agent and 1-2 parts of an additive. The pervious concrete provided by the invention has the advantages that the limestone powder is adopted for replacing pulverized coal in the original formula, dependence on the pulverized coal is greatly alleviated, production cost of concrete is reduced, and economic benefit is improved.

Description

technical field [0001] The invention relates to the field of concrete production, in particular to permeable concrete. Background technique [0002] With the development of concrete technology, maintaining ecological balance and realizing sustainable development are also the pursuit goals in the field of building materials. Permeable concrete is an ecological and environmentally friendly concrete. It not only has a certain strength, but also has a certain degree of water permeability and air permeability. With the use of permeable concrete, water can quickly penetrate into the ground, and the road will not accumulate water and reflect light in rainy days, thus well mitigating the impact of impermeable pavement on the environment. [0003] Permeable concrete generally consists of cement, coarse aggregate, water and admixtures. In recent years, due to the application advantages of pervious concrete, a lot of research has been done on it. For example, CN101190833A discloses ...
