Preparation process of environment-friendly water-permeable brick

Abstract

The invention provides a preparation process of an environment-friendly water permeable brick. The environment-friendly water permeable brick comprises the following components in parts by weight: 50to 55 parts of coal ash, 10 to 30 parts of coal gangue, 23 to 30 parts of furnace slag and 8 to 20 parts of water. The preparation process has the beneficial effects that problems in treatment of thecoal ash and the furnace slag are solved, the environment and cultivated land resources are protected, good economic benefits and environmental protection benefits are achieved, and the added value ofthe brick is high; and the prepared water permeable brick has good water permeability and moisture retention performance, can effectively solve the problems of urban heat island effect and waterlogging, and has good application prospects.

Description

technical field [0001] The invention relates to a preparation process of an environment-friendly permeable brick. Background technique [0002] Permeable brick is a new century environmental protection building material product grandly born to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. It is mainly used for municipal, important projects, and pedestrian walkways, squares, parking lots, etc. Site pavement; traditional permeable bricks use concrete as the production material, and the production cost is high, resulting in low economic benefits. With the rapid development of industry, the discharge of fly ash continues to increase. If it is not used effectively, It will cause greater harm to the environment and human health, and cause greater waste; at the same time, the process for producing permeable bricks in the prior art has cumbersome steps, and in the production process, the production efficiency ...

[0002] Permeable brick is a new century environmental protection building material product grandly born to solve urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance. It is mainly used in municipal, important projects, and pedestrian walkways, squares, and parking lots in residential areas. Pavement of the site; traditional permeable bricks use concrete as the production material, and the production cost is high, resulting in low economic benefits. With the rapid development of industry, the discharge of fly ash continues to increase. If it is not used effectively, It will cause greater harm to the environment and human health, and cause greater waste; at the same time, the process for producing permeable bricks in the prior art has cumbersome steps, and in the production process, the production efficiency is low, and the strength and pressure bearing capacity are relatively high.
