Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

Abstract

The invention discloses a regenerated building material, which is prepared from the following ingredients in parts by weight: 20 to 35 parts of cement, 50 to 75 parts of recycled aggregate, 0.6 to 1.2 parts of flame retardant, 1 to 3 parts of thickening agent, 2 to 6 parts of compatilizer, 1.5 to 4.5 parts of glass fiber and 1.2 to 2 parts of alkylphenol polyoxyethylene ether surface treating agent. According to the invention, construction waste is used as recycled aggregate, waste materials are introduced into an ecological circulation system, sustainable development is realized, the pollution to the environment is reduced, and the cost of raw materials is also reduced; the flame retardant is added in the production of the regenerated building material, so that the fireproof performance of the building material is improved, and the performance of the building material is improved; and the cement and the thickening agent are added, so that the characteristics of excellent strength, hardness, wear resistance, impact resistance, flexibility, freezing resistance, water resistance and the like of the original material are maintained, the workability, construction performance, bonding strength, thermal deformation performance and impermeability of the material are enhanced, and the potential safety hazard of the product in use is eliminated.

Description

technical field [0001] The invention relates to the technical field of recycled building materials, in particular to a recycled building material. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] Construction waste refers to the construction waste produced by man-made or natural reasons in the project, including waste slag, spoil, residual mud and waste materials, etc. These materials are of no ...
