Problems solved by technology

They add materials at one time, regardless of the surface layer, resulting in waste of pigments; due to the lack of compactness during machine pressing, the brick body has large gaps, resulting in serious water seepage, similar to water seepage
There are also disadvantages such as not wear-resistant and not frost-resistant
Due to the large-scale use of the above-mentioned pavement bricks to lay hard pavements in cities, the phenomenon of underground water shortage in large cities has caused the growth of trees and flowers to be sluggish, and the urban ecological environment has b

Abstract

An environmentally protection type color pavior brick for sidewalk is composed of the bottom layer prepared from broken stone, sand, cinder, silicate rock powder, active alumine, hydrogen peroxide, polyvinyl alcohol, water cement and calcium lignosulfonate, and the surface layer prepared from high-grade cement, iron oxide pigment, barium sulfate, white broken stone or sand, cinder, active alumine, hydrogen peroxide, vinyl alcohol, water and carbon black or zinc oxide. Its advantages are high penetability to rain and oil, high absorptivity to UV and irradiated heat, and high strength.

Description

Technical field: [0001] The invention relates to a building material, in particular to a pavement brick used for urban sidewalks. Background technique: [0002] At present, the pavement bricks laid on urban sidewalks are mainly dense mortar concrete structures, which are divided into two types: one is colored glazed bricks, and the characteristic surface layer is bright and bright. However, its production cost is high, and it cannot be maintained with water to protect the bright color of the surface. In addition, it has disadvantages such as poor strength and short service life. The other is machine-pressed brick with rough surface and dull color. The reason for the dim color is that the cement slurry overflows and mixes with the color during production. They add materials at one time, regardless of the surface layer, resulting in waste of pigments; due to the lack of compaction during machine pressing, the bricks have large gaps, resulting in serious water seepage, simila...
