Abstract

The invention discloses waste textile fiber heat-insulating bearing concrete, belonging to the field of building materials, and particularly relates to a fiber building material with the advantages of waste utilization, energy saving, environmental friendliness and high heat insulating performance, prepared from a heat insulating material, a waste fiber material and industrial residues, and a preparation method thereof. The bearing concrete is characterized in that: the heat insulating material is added by taking the preparation method of the building material containing waste fiber as an initial formula, so that the heat insulating performance of the original concrete is optimized; waste textile fiber is doped, so that the problem of waste treatment is solved, and the environmental pollution is lowered; and meanwhile, the hidden potential hazard of fire is avoided. By recycling waste textile fibers, a potential use of a textile material is developed, and the application field of the textile waste is expanded.
