Description

technical field [0001] The invention belongs to the field of building materials, and specifically relates to an inorganic geopolymer foam concrete, an ultra-light and high-strength geopolymer foam concrete sandwich composite thermal insulation wallboard prepared by using the inorganic geopolymer foam concrete, and their preparation method . Background technique [0002] Building energy consumption accounts for about 30% of my country's total energy consumption, and it shows an increasing trend year by year. The implementation of building energy conservation is particularly important and necessary for my country, which is short of energy resources. The use of thermal insulation materials is an effective way to achieve building energy conservation. Polyurethane foam boards and extruded polystyrene boards are currently the most widely used thermal insulation materials. They have the advantages of light weight, low thermal conductivity and good thermal insulation performance, bu...
