Abstract

The invention relates to a method for producing a waste residue foam concrete and nanopore vacuum plate composite material, and belongs to the fields of comprehensive utilization of resources and building materials. According to the invention, various industrial waste residues or sorted part of construction waste are used as the main raw material to produce a high-strength foam concrete and nanopore vacuum insulation plate composite material. Shock resistant sealing layer having self decorative function is formed by one-time pouring molding through placing a nanopore vacuum insulation plate in the foam concrete. The heat transfer capacity of the composite wall material is decreased by 100% than that of ordinary wall materials, so that the total thickness and the total weight of the wall are reduced by 30% or more. The invention solves a bottleneck problem that conventional wall materials of housing industry are inconvenient for installation. Because wall thickness and weight are reduced, the costs of steel structure and building foundation are reduced. The shock resistant strength of the wall material is greatly improved compared with wall materials of housing industrialization manufactured by conventional cement. The weather resistance is improved significantly.

Description

[0001] Technical field [0002] The invention belongs to the field of comprehensive utilization of resources and the field of building materials, and particularly relates to a method for making foam concrete by using various industrial waste residues and sorted construction waste, and compounding it with a nanoporous vacuum insulation board to make a composite wall material. technical background [0003] my country's rapid industrial development has led to a large amount of industrial solid waste stockpiling. According to the data provided by the "2010-2011 Comprehensive Utilization Development Report of Bulk Industrial Solid Waste", in 2011, the total volume of bulk industrial solid waste generated in my country was 3.46 billion tons, and the comprehensive utilization amount was 1.58 billion tons, with a net increase of 1.88 billion tons in that year. . In addition, according to the forecast of the Ministry of Industry and Information Technology's "Twelfth Five-Year Plan fo...
