Self-insulating building block containing aerated concrete building waste

Abstract

The invention discloses a self-insulating building block containing aerated concrete building waste. The self-insulating building block is prepared from the following raw materials in parts by mass: 5 to 9 parts of attapulgite, 60 to 80 parts of aerated concrete building waste, 3 to 5 parts of nano polytetrafluoroethylene, 0.5 to 0.9 part of nano nickel, 0.7 to 1.1 parts of tantalum carbide, 0.4 to 0.9 part of vanadium carbide, 0.9 to 1.1 parts of tungsten carbide, 1.2 to 1.5 parts of glass micro-beads, 30 to 45 parts of mixed solution I, an additive I accounting for 2 to 3 percent of the weight of the mixed solution I and an additive II accounting for 0.03 to 0.04 percent of the weight of the mixed solution I, wherein the mixed solution I comprises acrylic acid, polyvinyl alcohol, modified wheat straw and water. The self-insulating building block containing the aerated concrete building waste has the beneficial effects that the thermal performance is excellent, the weight is light, the strength is high, the early strength is high, the insulating performance is excellent, the product water absorption rate is low, no secondary byproduct is produced, the waste is used, the environmental protection is realized, and the delivery cycle of the building block is greatly shortened.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a self-insulating block containing aerated concrete construction waste. Background technique [0002] The advantage of external wall self-insulation and thermal insulation blocks is that it is accompanied by the theme construction, the overall construction timeliness of the project is high, the masonry is convenient, and the cumbersome process of secondary thermal insulation is eliminated, the construction cost is reduced, and the price is relatively low. New wall materials sintered with river and lake silt and composite blocks produced from fly ash, slag, coal gangue and other materials have been fully utilized in our country. Standard bricks are used for load-bearing walls and perforated bricks are used for frame structure infill walls. The existing problem is that the wall cannot meet the energy-saving and thermal insulation effect of 50% of public buildings and 65% of re...
