Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to an energy-saving and heat-resisting concrete block for building and a preparation method thereof. Background technique [0002] Thermal insulation concrete, also known as aerated concrete, foam concrete, and foamed concrete, belongs to the category of thermal insulation materials. It covers the surface of thermal equipment and pipelines, which can prevent or reduce heat exchange with the outside world and reduce heat dissipation. Special concrete with certain physical and mechanical properties. [0003] Insulation concrete is a member of the concrete family. It has the properties of low density, light weight, heat preservation, sound insulation, and earthquake resistance. It is a new type of building material. The basic raw materials of foam concrete are cement, lime, water, and foam, and some fillers, aggregates, and admixtures are added on this basis. Commonly used...
