Production technology for producing sintered wall bricks or building blocks with glaze on surfaces from construction waste

Abstract

The invention discloses a production technology for producing sintered wall bricks or building blocks with glaze on surfaces from construction waste and belongs to the technical field of recycling of construction waste for brick production. Green bricks are produced from bricks, concrete blocks, viscous spoil and other construction waste as well as garden waste, trees, plant straw, rice chaff, sawdust or waste in paper mills, sugar refineries and coffee plants and other mixtures of plant materials, and molded green bricks (green building blocks) or dried and preheated green bricks (green building blocks) or sintered bricks (building bricks) are glazed and fired. With the adoption of the method, the construction waste, the garden waste and industrial waste are utilized effectively, the recycling efficiency of waste is improved, glaze application is easier due to addition of plant materials, glaze can permeate micropores in surfaces of the bricks (building blocks), glaze layers and the bricks are bonded more closely and firmly, and the probability of falling of glaze in the later period is far lower than that of existing exterior wall tiles.

Description

technical field

[0001] The invention relates to the technical field of recycling construction waste to make bricks, in particular to a production process for making glazed sintered wall bricks or blocks by using construction waste. Background technique

[0002] In the prior art, recycled aggregates produced after recycling demolition construction waste are generally used as fillers, or as raw materials for pressing blocks or bricks, or combined with cement and other bonding materials to form concrete-like aggregates. building components. At present, a large amount of clay-based construction waste produced by foundation pit soil, subways, and underground projects is an unsolvable problem in various places. How to turn construction waste, especially spoil-like construction waste into treasure, is an urgent problem that needs to be solved.

[0003] In addition, after existing bricks and blocks are applied to buildings, a layer of thermal insulation material will be added on th...
