Problems solved by technology

[0002] At present, under the rapid development of my country's economy, rural urbanization and old city renovation have produced a large amount of construction waste, and industrial development has also produced a large amount of waste, such as phosphate slag, coal ash, etc. These construction waste and industrial waste Disposal has become a big problem at present, and most of them still use disposal methods such as burial, which is a fatal threat to the environment

Embodiment

[0008] Embodiment, a kind of construction waste brick-making method is characterized in that: its raw material ratio is, removes 30-57 parts of construction waste debris with a particle diameter of less than 14 mm, 20-40 parts of coal gangue particles, and a particle diameter of less than 1 mm. 10-15 parts of slag material, 8-15 parts of cement, 0.6-0.8 parts of quicklime, 3-18 parts of fly ash, 0.01-0.025 parts of hydroxysilicone sealing and curing agent, 8-12 parts of water, and 0.1-0.2 parts of sodium silicate. The construction waste debris can be old building demolition or new building waste. Antifreeze or antifreeze chlorine salt can also be added to the raw material ratio. Further speaking, firstly, the proportioning raw materials are processed

[0009] For construction waste, it is necessary to remove its metal objects, then crush it, and then screen it until the particle diameter is less than 12mm. For phosphate rock slag, it is necessary to screen the particle diamete...

Abstract

The invention discloses a method for making bricks by using construction wastes. The bricks are characterized by comprising the following raw materials: 30-57 parts of crushed aggregates of construction wastes of which the metal particles are removed and the diameter is small than 14mm, 20-40 parts of coal gangue particles, 10-15 parts of phosphate slag with the particle diameter being less than 1mm, 8-15 parts of cement, 0.6-0.8 part of quick lime, 3-18 parts of pulverized fuel ash, 0.01-0.025 part of a hydroxyl silicon sealed curing agent, 8-12 parts of water and 0.1-0.2 part of sodium silicate. The crushed aggregates of construction wastes can be dismantled materials of old buildings or wastes of novel buildings, and an anti-freezing agent or an anti-freezing chlorine salt can be added into the raw materials. The method has the advantages that the proportioning is simple, the energy is renewable, the environment is protected, and the wastes are utilized.

Description

technical field [0001] The invention relates to the technical field of renewable resources, in particular to a method for making bricks from construction waste. Background technique [0002] At present, under the rapid development of my country's economy, rural urbanization and old city renovation have produced a large amount of construction waste, and industrial development has also produced a large amount of waste, such as phosphate slag, coal ash, etc. These construction waste and industrial waste Disposal has become a big problem at present, and most of them also adopt disposal methods such as burying, which is a fatal threat to the environment. Contents of the invention [0003] The purpose of the invention is to provide a method for making bricks from construction waste, which has the characteristics of waste utilization and energy regeneration. [0004] The technical solution adopted in the present invention is: a method for making bricks from construction waste...
