Abstract

The invention discloses a recycled pavement brick and a preparation method thereof, and belongs to the technical field of building materials. The recycled pavement brick is prepared from the followingraw materials in parts by weight: 10-40 parts of recycled aggregate of construction wastes, 10-20 parts of gravel, 5-15 parts of a gelling agent, 10-20 parts of a water reducer, 5-15 parts of coal gangue particles, 5-15 parts of steel fiber, 5-15 parts of polypropylene fiber, 5-15 parts of quick lime, 20-80 parts of cement, 60-120 parts of water and 10-20 parts of polyamide. The recycled pavementbrick provided by the invention has the advantages of being high in strength, good in abrasion resistance, stable in quality, long in service life, low in cost, and capable of turning waste into treasure, protecting the environment and saving energy, thereby having good economic benefits and extensive social benefits.

Description

technical field [0001] The invention relates to a recycled 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. The regenerated pavement brick of the invention has high strength, good wear resistance, stable quality, long service life, low cost, can turn waste into wealth, is environmentally friendly and energy-saving, and h...
