Method for manufacturing building material from building garbage

Abstract

The present invention relates to a method for manufacturing the building material with the building garbage, the method executes sorting, magnetic separation, primary crushing and gravity sorting to the city building material, and the building material is separated to heavy material, light material and mineral material, the mineral material is used for manufacturing the building material after the secondary crushing, and the raw material of the building material comprises the following components: fiber material 5-10 parts, mineral material 40-60 parts, low-water cement 20-30 parts and other material 0-30 parts, the production process of the building material comprises the steps of mixing the fiber material, mineral material and other material to uniform, then adding the low-water cement for mixing to uniform, adding water and stirring to slurry, placing into the mold for jolt molding or extrusion molding, and forming the building used sheet material after natural curing. The method of the invention has the advantages of full utilization of the mineral material comprising the major component of the building garbage, saving the material resource, reducing the final discharging amount of the building garbage, and the method can be used for manufacturing the building materials such as hollow brick, hollow block, partition plate and the like.

Description

technical field [0001] The invention relates to a method for manufacturing building materials by using construction waste, and belongs to the fields of environmental protection and building materials. Background technique [0002] Construction waste is mainly inorganic mineral-based waste generated in the process of building renovation and demolition of buildings. According to existing regulations, these wastes should be concentrated in a special treatment site for treatment. There are two common ways to deal with them. One is to be piled into the garbage dump; the other is to be used as a cushion for temporary construction roads, and finally to be removed to the garbage dump. Due to the non-degradability of construction waste, the accumulation of construction waste will occupy a large amount of space and cause problems such as blowing sand. On the other hand, due to the continuous development of the construction industry, the production of building materials needs to consu...
