Abstract

The invention belongs to the technical field of construction materials and discloses a construction waste recycled pavement brick and a preparation method thereof. The construction waste recycled pavement brick is prepared from, by weight, 20-40 parts of construction waste recycled aggregate, 10-20 parts of a reinforcing agent, 10-16 parts of a water reducing agent, 5-15 parts of talcum powder, 10-20 parts of unsaturated polyester resin, 5-15 parts of clay, 10-20 parts of a hydroxyl silicon seal curing agent, 20-60 parts of coal gangue particles, 20-60 parts of water and 20-30 parts of polyamide. The construction waste recycled pavement brick has advantages of high strength, high abrasion resistance, stable quality, long service life, low cost, waste recyclability, environmental friendliness, energy saving, high economic benefits and extensive 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. At present, the traditional open-air stacking and deep excavation are the main methods of dealing with construction waste. Although this method has a large processing volume, is convenient and simple, and has low processing costs, it actually occupies land resources. If construction waste cannot be recycled in time, it will not only pollute the environment, but also cause a waste of resources. Contents of the invention [0003] One of the objectives of the present invention is to provide a recycled pavement brick from construction waste. The construction waste regenerated pavement brick of the present invention has high strength, good wear resistance, stable quality, long service life, low cost, can tur...
