Abstract

The invention discloses a pervious concrete brick with high strength. The brick comprises the following raw materials: ordinary portland cement, broken stones, phosphogypsum, lithium slag powder, steel slag, coal ash, silica fume, iron tailing sand, metakaolin, mixed fibre, straw powder, a water reducer, poly(styrene-co-butadiene), a silicone acrylic emulsion, redispersible latex powder, macroporous resin, an epoxy resin adhesive, ethylene diamine tetra (methylene phosphonic acid) sodium, diisopropanolamine, sodium hyposulfite, calcium lignin sulphonate, and water. The pervious concrete brick with high strength has the advantages of high compressive strength, excellent water permeability, and good frost resistance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-strength permeable concrete brick. Background technique [0002] Permeable concrete is usually also called porous concrete. It is a porous material with a certain material strength and a certain degree of water permeability and air permeability. From its own performance, in addition to effectively alleviating surface water It has obvious effects in rainwater purification and reduction of road noise. Permeable concrete generally has the following advantages: sound absorption and noise reduction, protection of groundwater, improvement of thermal environment, improvement of surface soil ecological environment, etc. However, when the water permeability of existing permeable concrete meets the requirements, the strength often cannot meet the requirements of use, which limits the application of concrete bricks made of it. Contents of the invention [0003] Based on the tech...
