Problems solved by technology

At present, construction waste is mainly treated by traditional open-air stacking and deep excavation for landfill. Although this method has a large processing capacity, is convenient and simple, and has low processing costs, it actually occupies a large amount of land resources and produces irreparable environmental pollution.
If such a large amount of construction waste cannot be recycled in time, it will not only pollute the environment, but also cause a serious waste of resources.

Abstract

The invention discloses regenerated bricks and a preparation method thereof and belongs to the technical field of building materials. The regenerated bricks are prepared from the following raw materials in parts by weight: 20 to 40 parts of construction waste recycled aggregate, 5 to 15 parts of an aggregate modifier, 5 to 15 parts of a gelatinizing agent, 10 to 20 parts of a water reducer, 10 to20 parts of magnesia carbon brick regenerated grains, 10 to 20 parts of steel fibers, 5 to 15 parts of zeolite powder, 5 to 15 parts of furnace slag, 30 to 70 parts of cement, 30 to 90 parts of waterand 5 to 15 parts of polyamide. The regenerated bricks disclosed by the invention have the advantages of high strength, good wearing resistance, stable quality, long service life and low cost; wastescan be changed into valuable things, and environment protection and energy saving are realized; the regenerated bricks have very good economic benefits and wide social benefits.

Description

technical field [0001] The invention relates to a recycled brick and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Construction waste is the main component of urban waste, accounting for about 30%-40% of the total urban waste. In 2004 alone, my country produced about 6 billion tons of construction waste, and the data from 2008 to 2011 must be far greater than this number. At present, construction waste is mainly treated by traditional open-air stacking and deep excavation and landfill. Although this method has a large processing capacity, is convenient and simple, and has low processing costs, it actually occupies a large amount of land resources and produces irreversible environmental pollution. If such a large amount of construction waste cannot be recycled in time, it will not only pollute the environment, but also cause a serious waste of resources. Contents of the invention [0003] One of the obj...
