Abstract

The invention discloses a sponge city ecological water-permeable pavior brick. The sponge city ecological water-permeable pavior brick comprises a sand foundation surface layer and a cement concrete structural layer. The sand foundation surface layer comprises, by weight, 50 to 100 parts of coated sand, 8 to 12 parts of polyether sulfone resin, 2 to 4 parts of glass fiber, 20 to 30 parts of epoxy resin, and 5 to 10 parts of alkali lignin. The cement concrete structural layer comprises, by weight, 60 to 80 parts of cement, 50 to 75 parts of fly ash, 80 to 100 parts of quartz sand, 20 to 40 parts of pitchstone powder, 1 to 6 parts of yellow dextrin, 5 to 10 parts of polypropylene fiber, 1 to 4 parts of a water reducing agent, and 40 to 50 parts of water. The invention also discloses a preparation method of the sponge city ecological water-permeable pavior brick. The sponge city ecological water-permeable pavior brick possesses excellent water permeability, wear resistance, and slip resistance, high flexural and compressive strength, and high temperature resistance, and is low in preparation cost.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a sponge city ecological permeable pavement brick. Background technique: [0002] With the development of the economy, the surface of modern cities is more and more covered by buildings and concrete. This "hardening" of the surface makes it difficult for atmospheric precipitation to penetrate into the ground in time, and the surface runoff increases, forming the "heat island effect". As well as environmental problems such as waterlogging and urban surface subsidence caused by insufficient drainage. As an environmental material, porous permeable bricks are applied to the paving of roads and squares, which can allow part of the precipitation to infiltrate into the ground and reduce surface runoff, thus better solving the above problems. [0003] In my country, the total area of ​​desert is about 637,000 km 2 , Accounting for about 6.8% of the country's land, mainly distributed ...
