Abstract

The invention discloses a preparation method of a high-compressive-strength composite water-permeable brick, and belongs to the technical field of water-permeable brick preparation. According to the method, a macroscopic stacking structure composite material composed of cement, powder, aggregate, fly ash, fabric fragments and the like is used, and in the process of forming the water permeable brick, the water permeability of the water-permeable brick is improved; the water bleeding property of cement paste can be adjusted by the fabric fragments; epoxy resin and a curing agent are added, and the curing agent is used for crosslinking the epoxy resin into reticulate huge molecules; surface treatment is carried out on inorganic filler by using a silane coupling agent, the silane coupling agent enhances the binding force between sand particles and an adhesive, so that the strength of a whole brick body is improved; then, the fly ash and the sugar filter mud are added, sugar filter mud continues to be added, and the main component of the sugar filter mud is calcium carbonate, so that calcium carbonate in the sugar filter mud is decomposed to generate carbon dioxide at a certain high temperature; staggered through holes are formed in the brick body, so that water easily permeates the brick body, then the water permeability of the water-permeable brick is improved, and the brick has wide application prospects.

Description

technical field [0001] The invention discloses a preparation method of a high compressive strength composite permeable brick, belonging to the technical field of permeable brick preparation. Background technique [0002] Permeable bricks originated in the Netherlands. During the process of building the city from the sea, the Dutch found that the ground after the sea water was drained would cause continuous land subsidence due to long-term lack of contact with water. Once the dykes on the coastline are washed away, the seawater will quickly rush to cities much lower than sea level and submerge the entire coastal city. [0003] Permeable bricks are roughly divided into the following categories: Ordinary permeable bricks: porous concrete materials made of ordinary crushed stones are pressed and formed, used for sidewalks and squares in general blocks, and are general paving products. Polymer fiber concrete permeable brick, colored stone composite concrete permeable brick, colo...
