Problems solved by technology

Although permeable bricks can infiltrate ground moisture into the ground in rainy days, if they cannot evaporate in time after rain, the air in the city will be dry and the surface temperature will be high.
[0007] Up to now, the relevant technology of preparing water-storage square bricks with fly ash, desulfurized gypsum and silicon carbide slag industrial waste is still blank.

Abstract

The invention provides a water storage type recycled industrial waste residue plaza brick. The water storage type recycled industrial waste residue plaza brick is made by adopting a main material, a water reducer, a binding agent and running water, wherein the main material is prepared from the following raw materials in percentage by mass: 50-68% of desulphurizing gypsum, 20-30% of coal ash, 5-13% of silicon carbide residue, 2-7% of quick lime and 1-5% of cement. The invention also provides a method for preparing the water storage type recycled industrial waste residue plaza brick comprises the following steps: firstly preparing the main material; secondly, preparing blank; thirdly, carrying out compression moulding and maintenance, so that the water storage type industrial waste residue plaza brick is obtained. The water storage type recycled industrial waste residue plaza brick not only is high in strength but also can realize a water storing function, so that industrial waste residue is well utilized, influence of the industrial waste residue to the environment can be reduced, influence to running water on pavement is reduced, rainwater can be timely evaporated in sunny days, a surface water system is effectively restored, air quality is improved, and ecological cycle function of the pavement is improved.

Description

technical field [0001] The invention belongs to the technical field of building brick materials, and in particular relates to a water-storage-type industrial waste slag regenerated square brick and a preparation method thereof. Background technique [0002] For the beautification of modern cities, square bricks have become the structural bricks laid on urban roads, squares, residential quarters, tourist areas and other roads. Ordinary square bricks are mostly made of cement and sand and stones. This kind of bricks wastes a lot of resources, is expensive, and has poor water permeability. Most of them are permeable structures and do not have the function of water storage. [0003] In view of the waste of resources and high price of ordinary bricks, researchers at home and abroad have used cheap industrial waste slag instead of cement to make bricks, for example: patent CN201110167367 "A lightweight brick made of fly ash and its manufacturing method" Fly ash bricks are prepare...
