Building brick containing building waste recycled materials and manufacturing method of building brick

Abstract

The invention belongs to the technical field of building material processing, and particularly relates to a building brick containing building waste recycled materials and a manufacturing method of the building brick. The building brick comprises the following raw materials in parts by weight: 20-25 parts of building waste recycled materials, 12-16 parts of cement, 4-6 parts of fly ash, 3-4 partsof coal slag, 6-8 parts of slaked lime, 2-3 parts of modified glass fibers, 10-12 parts of quartz sand and 3-6 parts of novolac epoxy resin. Building waste is recycled to manufacture the building brick, the problems of environmental pollution, land resource occupation and the like caused by building waste stacking can be effectively reduced, the building waste is used as a raw material for producing the building brick after subjected to the steps of primary separation, winnowing, magnetic separation, ball milling and the like, the waste of resources can be effectively reduced, and the production cost is saved. In the magnetic separation step, iron substances can be recycled, so that separation of the iron substances in a concrete structure and the concrete structure can be realized, namelyrecycling of resources is realized.

Description

technical field [0001] The invention belongs to the technical field of building material processing, and in particular relates to building bricks containing recycled building waste and a production method thereof. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. [0003] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1 / 3 of the total urban waste. [0004] With the increase in the amount of urban construction waste, the number of garbage dumps is also increasing, and the area of ​​the garbage dump is also gradually expanding. The phenomenon of garbage and people c...

Problems solved by technology

The phenomenon of garbage and people competing for land has reached a very serious level. Most of the suburban garbage dumps are mainly piled in the open air. After long-term exposure to the sun and rain, harmful substances in the garbage (including urban construction waste) Polycyclic aromatic hydrocarbons released from paints, coatings and asphalt) seep into the soil through landfill leachate, resulting in a series of physical, chemical and biological reactions, such as filtration, adsorption, precipitation, or absorbed by plant roots or by microorganisms Synthetic uptake, causing pollution of suburban soil, thereby reducing soil quality
