Abstract

The invention relates to a construction waste recycled imitation stone brick, the structure of the recycled imitation stone brick comprises a surface layer and a base layer, the base layer comprises the following raw materials: ash cement, a compound of 0-5mm recycled tile aggregate and recycled concrete aggregate, a compound of 5-10mm recycled tile aggregate and recycled concrete aggregate, and an auxiliary agent, the surface layer is prepared from the following raw materials: grey cement or white cement, 0-5mm and 5-10mm recycled concrete aggregate compounds, pigment and auxiliaries. According to the construction waste recycled imitation stone brick developed by the invention, construction waste recycled bricks and tiles and concrete aggregate are used as the base layer and the surface layer aggregate, all indexes meet the requirements of the national standard GB28635-2012 Concrete Pavement Brick through the design of the base layer mix proportion, the product strength is not lower than 40MPa, the cost of the imitation stone brick is greatly reduced, and the production cost is reduced. And high value-added utilization of the construction waste in high-end imitation stone products is realized.

Description

technical field [0001] The invention relates to a construction waste regenerated imitation stone brick and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Because of its gorgeous natural appearance and durable properties, natural stone bricks use a large number of stone bricks for public buildings, roads, and residential landscapes. Stone brick decoration plays an indelible role in landscape construction. However, the development of natural stone is accompanied by a series of ecological and environmental problems such as vegetation destruction, soil erosion, water and soil pollution, and geological disasters, which cause great damage to the natural environment, so it is subject to more and more restrictions. Coupled with the non-renewable natural resources, the price of natural stone bricks continues to rise. In this situation, imitation stone brick products become a substitute. However, at present, the ra...
