Abstract

The invention discloses a rolling-formed fly ash-construction waste slab material and belongs to the technical field of preparation of building materials. The slab material comprises a surface layer and a middle material layer, wherein glass fiber grid cloth is laid between the surface layer and the middle material layer. According to the rolling-formed fly ash-construction waste slab material, industrial waste residues and construction wastes serve as raw materials, so that the slab material has the characteristics of high solid waste utilization ratio, low price and low cost; and the potential hydration activity of fly ash and the construction wastes is fully used, so that the waste is changed into the valuable. The rolling-formed fly ash-construction waste slab material has the characteristics of light weight, high strength, low hydration heat, high shock resistance, low shrinkage, good fatigue resistance, high carbonization resistance, good durability and the like, thereby being capable of being extensively applied to the construction fields of interior wall slabs, exterior wall slabs and the like.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a roller-formed fly ash construction waste plate. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly. Accompanied by this is the increasing amount of construction waste. A large amount of construction waste not only occupies the land, but also brings serious pollution to the human living environment. According to statistics, my country will add more than 40 million tons of construction waste every year, and the amount of construction waste has accounted for more than 1 / 3 of the total urban waste, of which concrete construction waste has accounted for more than 40% of construction waste. This phenomenon has been widely concerned by the whole society. The long-term stockpiling of construction waste not only wastes land resources, is prone to safety hazards...
