Description

Technical field: [0001] The invention relates to the technical field of building materials, in particular to a high-strength and high-permeability pavement brick. Background technique: [0002] With the intensification of urbanization, the urban surface is gradually being covered by buildings and various concrete and other water-repelling materials, 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 rapidly. [0003] As a new ty...
