Eco-friendly pavior brick and preparation method thereof

Abstract

The invention provides an eco-friendly pavior brick and a preparation method thereof, and relates to the technical field of pavior brick production. The pavior brick comprises a surface layer and a base layer, wherein the surface layer is prepared from, by weight, 15-27 parts of cement, 15-30 parts of grit, 5-7 parts of macadam, 30-40 parts of industrial waste cinder granules, 12-16 parts of waste ceramic particles, 3-6 parts of silica fume, 5-10 parts of coal ash, 3-10 parts of lime, 2-4 parts of air-entraining agents, 1.5-2.5 parts of waterproof agents, 0.3-0.5 part of antifreezing agents, 0.4-0.6 part of water reducing agent, 0.3-0.5 part of pigment powder and 1-3 parts of water; the base layer is prepared from, by weight, 16-18 parts of cement, 18-22 parts of grit, 17-25 parts of macadam and 2-3 parts of water; the preparation method includes the steps of (1) the preparation of surface layer ingredients, (2) preparation of base layer dosing, (3) molding, demoulding, stacking and maintaining; the eco-friendly pavior brick and the preparation method thereof solve the problems of unavailable recycling of wastes, poor heat insulation property, low water permeability and freezing resistance, a bad effect of reducing water and low compressive strength in the prior art.

Description

technical field [0001] The invention belongs to the technical field of pavement brick production, and in particular relates to an environment-friendly pavement brick and a preparation method thereof. Background technique [0002] Pavement brick is a kind of paving material, which is mainly made of cement, stone and sand through processing, vibration and pressure or other molding processes, and is used for laying concrete pavement and ground engineering of urban road sidewalks, city squares, etc. Blocks, boards, etc., have a wide range of applications, and the consumption of daily materials is very large, so there is an urgent need to increase revenue and reduce expenditure. [0003] A large part of construction waste and industrial waste is piled up in a certain corner of the city as urban waste, which not only fails to realize the value of recycling, but also occupies urban land and pollutes the environment, seriously restricting the development of the city. [0004] In ad...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of existing pavement bricks that cannot be reused by waste, poor heat insulation, poor water permeability, poor antifreeze, poor water reducing effect and low compressive strength, the purpose of the present invention is to provide an environmentally friendly pavement brick and its preparation method , the prepared environmentally friendly pavement bricks have the advantages of good water resistance, high compressive strength, good wear resistance, energy saving and environmental protection
