Abstract

The invention provides an ecological water-permeable road pavement brick and a preparation method thereof, and relates to the technical field of production of road pavement bricks. The ecological water-permeable road pavement brick comprises a surface layer and a base layer, wherein the surface layer is prepared from the following raw materials in parts by weight: 20 to 30 parts of cement, 25 to 30 parts of sand, 5 to 10 parts of crushed stone, 4 to 6 parts of building waste residue coarse aggregate, 3 to 6 parts of volcanic ash, 6 to 10 parts of glass powder, 5 to 10 parts of fly ash, 3 to 10 parts of clay, 0.4 to 0.6 part of water reducing agent, 0.3 to 0.5 part of pigment powder, and 1 to 3 parts of water; the base layer is prepared from the following raw materials in parts by weight: 22 to 30 parts of cement, 18 to 32 parts of sand, 17 to 23 parts of crushed stone, and 2 to 3 parts of water. The preparation method comprises the following steps of (1) preparing of the materials of the surface layer; (2) preparing of the materials of the base layer; (3) forming, demolding, stacking and curing. The ecological water-permeable road pavement brick can solve the problems of failure to reutilize the wastes, poor water permeability, low compressive strength and poor abrasion-resistant property in the existing road pavement.

Description

technical field [0001] The invention belongs to the technical field of pavement brick production, and in particular relates to an ecological permeable 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...
