Problems solved by technology

[0003] In addition, after existing bricks and blocks are applied to buildings, a layer of thermal insulation material will be added on the outside, and finally the outer wall will be pasted with a layer of ceramic tiles, ceramic wall tiles or used in the outermost layer for decoration. After a long period of time, these tiles and ceramic wall tiles will easily fall off

Example Embodiment

[0102] Example 1

[0103] The production process of using construction waste to make sintered wall tiles with glaze on the surface of the present invention includes the following steps:

[0104] a. Recycle and remove the construction waste (including the demolished bricks and concrete blocks) on the ground, and separate the spoil, bricks and concrete blocks in the construction waste, and crush and screen the bricks and concrete blocks. Obtain the regenerated fine aggregate and fine powder of construction waste with a particle size of less than 1.5mm; classify the spoil into the spoil separated in step b for processing;

[0105] b. Recycle the cohesive spoil construction waste (including the clay spoil produced by various foundation pit excavation, underground pipe network, subway and other projects), remove impurities, and separate the sticky spoil and construction waste in the construction waste. Bricks and concrete blocks, the bricks and concrete blocks are classified into the bri...

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...
