Problems solved by technology

[0002] Most of the masonry bricks used in the construction industry are clay bricks, and there are also a small amount of blocks. The use of clay bricks has already caused a large amount of land to be occupied and lost. The urban area is used to dump and bury garbage. After dumping and burying construction waste, the farmland will be permanently unusable; in addition, a large amount of inorganic industrial waste is also occupying and swallowing land in large quantities; in addition, some urban sewage , Industrial wastewater is also continuously discharged, these are not only seriously damaging the environment, causing serious environmental pollution

Embodiment Construction

[0006] The present invention collects waste and old bricks and tiles, cement, soil, gravel and other inorganic building wastes and inorganic industrial waste residues, and crushes them with a jaw crusher (smaller ones can be processed by a wheel mill). According to different needs, the particle size gradation is obtained by sieving (generally, the wheel milling does not need to be sieved). When crushing, it can be single, or it can be mixed together regardless of proportion, and it can be crushed to a particle size below about 4mm (it can also be mixed first and then crushed regardless of proportion), and it can be single after crushing, mixing or crushing According to different molding methods, add 1-10% different amounts of slurry with bonding effect, and use ordinary mud mixer or mixer to make the two remix to make mud ball or wet In powder form, it is extruded or molded to make various required bricks and tiles, and then dried. Then, it is sent to a tunnel kiln for firing...

Abstract

The invention relates to a method for producing a new building material from construction waste and industrial residue. The method comprises the steps of crushing the waste and used materials, mixing the crushed waste and used material with different volumes of fluxed slurry with caking property according to different molding requirements so as to prepare a material which can be processed into bricks and tiles, then, shaping the material, and burning the shaped material, thereby producing the new building material.

Description

technical field [0001] The invention relates to water and soil conservation in the field of land resource protection, garbage disposal in the field of environmental protection, wall masonry materials and roof tiles in the field of building materials. Background technique [0002] Most of the masonry bricks used in the construction industry are clay bricks, and there are also a small amount of blocks. The use of clay bricks has already caused a large amount of land to be occupied and lost. The urban area is used to dump and bury garbage. After dumping and burying construction waste, the farmland will be permanently unusable; in addition, a large amount of inorganic industrial waste is also occupying and swallowing land in large quantities; in addition, some urban sewage , Industrial wastewater is also constantly discharged, these are not only seriously damaging the environment, causing serious environmental pollution. All of these are endlessly devouring the land and water r...
