Environment-friendly brick manufacturing process and mold

Abstract

The invention discloses an environment-friendly brick manufacturing process and a mold, and relates to the technical field of environment-friendly brick manufacturing, the environment-friendly brick comprises raw materials and water, the ratio of the raw materials to the water is 1: 0.55, and the raw materials comprise, by weight, 75% of building recycled aggregate, 20% of stone powder, 4%-5% of cement and 0.25% of mortar. The building recycled aggregate is used as a main material to replace river sand, so that the resource consumption is reduced, the raw material cost can be reduced, a largeamount of building garbage can be consumed, and the brick compressive strength is improved; moreover, when the stirred raw materials are fed into the mold, the mold can vibrate and tamp the raw materials, so that gaps in the raw materials are reduced, and the cracking rate during green brick maintenance is reduced; meanwhile, the temperature is gradually increased during curing, and constant-temperature curing is performed, so that the cracking rate during green brick curing can be further reduced.

Description

technical field [0001] The invention relates to the technical field of making environmentally friendly bricks, in particular to a manufacturing process and molds for environmentally friendly bricks. Background technique [0002] With the acceleration of urbanization and the construction of small towns, the renewal of urban residences, office buildings, commercial and industrial buildings and the scale of municipal relocation continue to increase. On the one hand, a large number of original old buildings have been demolished, resulting in a large amount of construction waste If the construction waste is measured by mass, concrete waste accounts for about 48.35%, waste bricks and stones account for 37.42%, and these two wastes account for 85.77% of construction waste. The best way to get rid of construction waste. On the other hand, upgrading and updating urban residences, office buildings, commercial and industrial buildings requires the use of a large amount of cement and br...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing environmentally friendly bricks use natural river sand as the main material, and then use stone powder, cement and other additives to make river sand bricks. Among them, river sand accounts for 60% and cement accounts for 10%. ~15%, a large amount of dredging river sand will not only cause soil erosion, but also accelerate resource consumption;

[0004] Moreover, when the existing river sand bricks are made, they are wet-mixed directly by adding water. Since the same raw materials will gather together when they are put in, they are easy to agglomerate directly after adding water, and it takes a long time to eliminate the agglomeration Stir evenly, and at the same time, when the mixed raw materials are sent into the mold, the mold does not have the function of automatically tamping the raw materials, and will not tamp the raw materials, so that there will be gaps inside the raw materials, which are easy to crack during maintenance
