Abstract

The invention relates to the technical field of preparation of building materials, in particular to a preparation method of a non-burnt environment-friendly water permeable brick. According to the preparation method, firstly, the porosity of basalt is modified and increased, and the pore diameter of the basalt is further broadened by utilizing an ice splitting function, so that the basalt has more abundant pore channels so as to be provided for water molecules to pass through, and the water permeation rate of a brick body can be increased by using the basalt as a raw material of the non-burnt environment-friendly water permeable brick; then, silicon hydroxyl groups are added on the particle surface of the basalt, high-bond energy chemical bonding can be generated by utilizing the silicon hydroxyl groups on the surface of the basalt and silicon hydroxyl groups in silicate cement, and the internal bonding strength of the non-burnt environment-friendly water permeable brick is increased, so that the problem that the mechanical performance of a common non-burnt water permeable brick is not ideal is solved; in addition, with the enhancement of the internal bonding strength, required compression molding pressure is reduced while the same molding effect is achieved, so that the porosity of the non-burnt environment-friendly water permeable brick is increased, the water permeability of the non-burnt environment-friendly water permeable brick is further increased, and a wide application prospect is obtained.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a method for preparing a fire-free environment-friendly permeable brick. Background technique [0002] With the acceleration of urbanization, the urban surface is gradually being covered by water-repelling materials such as buildings and various concretes, and the proportion of impermeable areas has increased significantly, and the coverage rate in some areas has exceeded 80%. As the drainage capacity of cities is getting worse and worse, when many cities encounter heavy rains, the rainwater on the roads cannot seep quickly, which can easily cause urban waterlogging. Therefore, in order to solve the problem of urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance, a new green and environmentally friendly building material product-permeable bricks emerged as the times require and have developed rapidl...
