Abstract

The invention discloses a roll-formed alkali slag and building rubbish plate, and belongs to the technical field of building material preparation. The roll-formed alkali slag and building rubbish plate comprises a surface layer and a middle material layer, and a fiberglass mesh is laid between the surface layer and the middle material layer. Industrial waste residues and building rubbish are adopted as raw materials, the advantages of being high in solid waste utilization rate and low in price and cost are achieved, the potential hydration activity of the alkali slag and the the building rubbish is fully utilized, and waste is turned into wealth. The roll-formed alkali slag and building rubbish plate has the advantages of being high in wear resistance, low in heat of hydration, high in impact resistance, low in contractibility rate, good in fatigue resistance, high in carbonization resistance, good in durability and the like, and can be widely applied to the building fields of inner wallboards, outer wallboards and the like. The process has the advantages of being simple, low in price and environmentally friendly, saving energy and the like, and is suitable for volume production.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a roll-formed alkali slag 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 hazar...
