Problems solved by technology

[0002] The implementation of building insulation is a major measure for energy saving and emission reduction and sustainable development in the future. Its development direction is self-insulation. However, due to the defects of various self-insulation building block products: either the structure is not good, or the structure itself is complex and costly. High, or the construction is inconvenient, so it cannot be popularized and applied
In the composite structure, although aggregates can be lightweight thermal insulation aggregates, the glued parts formed by cement and other cementitious materials become thermal bridges in self-insulating blocks, and their existence reduces the thermal insulation effect

Abstract

The invention provides a method for preparing a self-thermal-insulation concrete building block, and belongs to the technical field of preparation of building materials. The main body of the self-thermal-insulation concrete building block is a thermal insulation concrete structural frame; a plurality of sandwich cavities are enclosed on the outer wall and the inner wall of the frame; and organic light materials, inorganic light materials or organic-inorganic composite light materials are packed or filled in the cavities to form a thermal insulation core layer. The self-thermal-insulation concrete building block prepared by the method has high self-thermal-insulation performance, high shock resistance and high tenacity, is a structural material and a thermal insulation material and has remarkable effects of energy conservation, environment friendliness and reduction in building cost after being used.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a preparation method of a self-insulating concrete block. Background technique [0002] The implementation of building insulation is a major measure for energy saving and emission reduction and sustainable development in the future. Its development direction is self-insulation. However, due to the defects of various self-insulation building block products: either the structure is not good, or the structure itself is complex and costly. High, or the construction is inconvenient, so it cannot be popularized and applied. The above-mentioned situation of self-insulating blocks has led to most buildings still passively adopting secondary insulation, that is, after the building is completed, light-weight insulation materials such as foam plastic boards and rubber powder polystyrene concrete are applied externally or externally, and the construction vol...
