Brick regenerated by using construction waste

Abstract

The invention relates to the technical field of building waste resource utilization, in particular to a brick regenerated by using construction waste. The brick comprises a brick body; the brick regenerated by using the construction waste further comprises a pressing block and a first clamping block; the brick body, the pressing block and the first clamping block are all made of the following raw materials in parts by weight: 56-58% of waste brick powder, 3-5% of fly ash, 11-13% of quick lime, 17-19% of aggregate, 5.5-6% of an additive and 14-20% of water; an L-shaped groove is formed in the brick body; and one end of the L-shaped groove is communicated with the upper end face of the brick body, and the other end is communicated with one outer side wall of the brick body. The first clamping block is pushed by the pressing block to be clamped in a first rectangular groove of adjacent brick bodies, then the first clamping block and the other end of a second clamping block slide along the groove wall of a through groove and then move into a second rectangular groove of the adjacent brick bodies to be matched, and therefore the brick bodies on the road surface form a whole under the action of the first clamping block and the second clamping block, so that the flatness of the regenerated brick on the pavement is improved, and the condition that a certain brick body is loosened to cause ankle sprain of pedestrians is prevented.

Description

technical field [0001] The invention relates to the technical field of resource utilization of construction waste, in particular to a regenerated brick utilizing construction waste. Background technique [0002] After the construction waste is specially treated, crushed, graded and mixed in a certain proportion, the aggregate that meets the production requirements of different concrete products is recycled aggregate; the recycled aggregate can produce recycled aggregate with different particle sizes after crushing, screening and grading , usually the recycled aggregate is divided into coarse aggregate, fine aggregate and fine powder; compared with natural sand and gravel aggregate, recycled aggregate has the characteristics of high porosity, low apparent density and low strength; by adjusting the recycled bone The particle size distribution of the raw material, using red mud-slag cement as the cementitious material, controlling the water-binder ratio, and adding an appropria...

[0002] After the construction waste is specially treated, crushed, graded and mixed in a certain proportion, the aggregate that meets the production requirements of different concrete products is recycled aggregate; the recycled aggregate can produce recycled aggregate with different particle sizes after crushing, screening and grading , usually the recycled aggregate is divided into coarse aggregate, fine aggregate and fine powder; compared with natural sand and gravel aggregate, recycled aggregate has the characteristics of high porosity, low apparent density and low strength; by adjusting the recycled bone The particle size distribution of the raw material, using red mud-slag cement as the cementitious material, controlling the water-binder ratio, and adding an appropriate amount of composite additives, can prepare high-strength pavement bricks; Finally, the rainwater will take away part of the soil, resulting in a large amount of soil loss on the road surface, which in turn causes the road surface to be uneven, making some pavement bricks loose on the lost soil road surface, which in turn makes people walk on the road paved with pavement bricks Hidden danger of sprained feet

[0003] For example, a Chinese patent with the application number CN201920068225.9 discloses a pavement floor tile that can be spliced ​​to form a pavement, including a brick body, one end of the brick body is integrally formed with a rectangular bump, and the opposite rectangular bump is formed on the brick body. One end of the block is provided with a small rectangular notch, and the rectangular protrusion fits with the small rectangular notch, and one side of the brick body is integrally formed with two lower backing plates, and the height of the two lower backing plates is less than that of the brick body. height, the brick body is located at the opposite end of the two lower backing boards, and two upper backing boards are integrally formed, and the brick body is provided with a large rectangular notch corresponding to the position between the two upper backing boards; The rectangular bumps between the bricks and the small rectangular notches on the bricks are beneficial to ensure that the front and rear gaps of the bricks are the same. The upper backing plate is matched with the lower backing plate, and the large rectangular notch is matched with the position between the lower backing plates, so that the bricks The gap between the left and right sides of the body remains uniform, which improves the laying efficiency of the floor tiles and ensures that the surface flatness and height of the floor tiles are consistent; The bricks are separated, which will affect the strength of the bricks on the pavement. At the same time, if a certain ground is sunken as a whole, it will cause part of the bricks to sink, which will affect the smoothness of the pavement on which the pavement bricks are laid, and thus cause the limitation of this scheme. sex
