High-water-permeability environment-friendly water-permeable brick produced by utilizing industrial residues and preparation method thereof

Abstract

The invention discloses a high-water-permeability environment-friendly water-permeable brick produced by utilizing industrial residues, and belongs to the technical field of construction materials. The water permeable brick comprises a surface layer and a bottom layer, wherein the bottom layer is prepared from the following components in percentage by mass: 30-40 percent of fine-sand and pulverized fuel ash particles, 25-35 percent of dump slag, 10-20 percent of a concrete stone material and 15-25 percent of cement; the surface layer is prepared from the following components in percentage by mass: 15-20 percent of cement, 60-70 percent of quartz sands and 15-20 percent of decorative stone particles; the fine-sand and pulverized fuel ash particles are prepared from the following components in percentage by mass: 70-80 percent of pulverized fuel ash, 10-20 percent of fine sands, 0.1-0.15 percent of water glass and 5-10 percent of cement; and the grain diameters of the fine-sand pulverized fuel ash particles and concrete stone material are 2-4mm. The invention further provides a preparation method of the high-water-permeability environment-friendly water-permeable brick. The high-water-permeability environment-friendly water-permeable brick has the advantages of strong water permeability, good moisture retention, sliding prevention, high strength, cold resistance, weathering tolerance, noise reduction, sound absorption and the like.

Description

technical field [0001] The invention relates to a highly water-permeable environment-friendly permeable brick and a preparation method thereof, in particular to a highly water-permeable environment-friendly water-permeable brick produced by utilizing industrial waste residues and a preparation method thereof, belonging to the technical field of building materials.
