City sponge water permeable structure brick and production technology thereof

Abstract

The invention relates to the technical field of building materials, in particular to a city sponge water permeable structure brick and a production technology thereof. The city sponge water permeable structure brick comprises a bottom layer and a surface layer, wherein the surface layer is integrally formed at the upper surface of the bottom layer; the bottom layer is mainly prepared from the following raw materials in parts by weight: 80 to 120 parts of cement, 350 to 450 parts of fine sand, 400 to 550 parts of crushed stone, 50 to 100 parts of solid waste powder and 100 to 150 parts of water; the surface layer is mainly prepared from the following raw materials in parts by weight: 10 to 18 parts of cement, 25 to 45 parts of fine sand, 35 to 55 parts of crushed stone, 2 to 10 parts of white cement, 0.5 to 2 parts of pigment and 1 to 6 parts of water. The city sponge water permeable structure brick has the advantages that the problem of contradiction between mechanical property and water permeation rate of the water permeable brick is solved; the water permeable property, water retention rate and compressive strength are good, the utilization rate of wastes is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to building materials and relates to the technical field of permeable bricks, in particular to an urban sponge permeable structural brick and a production process thereof. Background technique [0002] With the rapid development of modern society and the improvement of people's living standards, the requirements for roads are also getting higher and higher. Nowadays, the traditional concrete structure is used in road construction to be dense, but it cannot absorb noise. The noise is too loud during the driving process of the vehicle, especially on rainy days. , seriously affecting the life and work of residents. The permeable brick is a new environmentally friendly building material product born to solve the hardening of the urban surface, create a high-quality natural living environment, and maintain the urban ecological balance. At the same time, the permeable bricks can release water vapor when the surface water evaporates, i...

AI Technical Summary

Problems solved by technology

However, the urban sponge permeable structural bricks in the prior art have the disadvantages of poor water permeability and water retention performance and low strength, and it is difficult to meet the needs of sponge city construction.
