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 a building rubbish regeneration pavior brick and a preparation method thereof, and belongs to the technical field of building materials. The pavior brick is prepared from the following raw materials, in parts by weight: 20-30 parts of building rubbish regeneration aggregate, 10-20 parts of an aggregate modifier, 5-15 parts of a gelling agent, 10-20 parts of a water reducing agent, 4-10 parts of coal gangue particles, 3-9 parts of fly ash, 4-10 parts of a hydroxy silicon seal curing agent, 3-9 parts of nano silicon dioxide, 50-100 parts of cement, 80-120 parts of water and 5-15 parts of polyamide. The building rubbish regeneration pavior brick is high in strength, good in wear resistance, stable in quality, long in service life, low in costs, and friendly to environment, saves energy, can turn wastes into wealth, and has extremely good economic benefits and wide social benefits.

Description

technical field [0001] The invention relates to a construction waste regenerated pavement 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. 2004 only [0003] my country produces 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 th...
