Abstract

The invention discloses a production process for a construction waste concrete porous brick; raw materials also include expanded vitrified micro-beads, the workability and thermal insulation performance of concrete can be improved, the water absorption rate and the shrinkage rate of the concrete are reduced, and the comprehensive performance of the porous brick is improved; after aging, the materials are tightly covered to make the materials mixed evenly; pores of a green brick of the porous brick are conical round pores, and thus masonry mortar can be prevented from entering the pores so as to prevent from affecting the thermal insulation performance of the porous brick; with control of the temperature and humidity of a constant-temperature and constant-humidity curing room, forming of the porous brick can be ensured. The porous brick produced by the production process has the advantages of high compressive strength, low heat conductivity coefficient, huge market potential and broad prospects.

Description

technical field [0001] The invention belongs to the production field of porous bricks, more specifically, the invention relates to a production process of construction waste concrete porous bricks. Background technique [0002] With the accelerated development of my country's industrialization and urbanization process, the construction industry is also developing rapidly at the same time, and the accompanying construction waste is also increasing. Construction waste is not garbage, but misplaced resources. Construction waste is mainly composed of inorganic non-metallic substances such as waste bricks, waste concrete, and waste mortar. In addition, there are a small amount of steel, wood, glass, plastic, etc. These substances are recyclable and reused. Most of the steel, wood, and plastic are recycled, and the utilization rate of the rest is extremely low. The use of construction waste mixed aggregates to produce concrete porous bricks, on the one hand, can solve the proble...
