Problems solved by technology

[0002] At present, the blocks that constitute the walls of buildings are basically hollow concrete blocks. Although the blocks of this hollow structure reduce the weight of the wall to a certain extent, there are the following problems: one is that it has a strong The heat-insulating performance of the wall is poor due to thermal bridge effect, and the hollow part of the wall formed by the stacked hollow blocks forms an air convection channel inside the wall, thereby further reducing the thermal insulation performance of the wall; Yes, the impact resistance and bearing strength are relatively weak, and it is easy to produce micro-cracks or even cracks; the third is that the waterproof performance is not good, and the moisture content of the wall will change with the change of the ambient humidity, thus affecting the frost resistance of the wall. adverse effect on durability

Abstract

The invention relates to a building block. The building block comprises a skeleton and a core body, wherein the skeleton and the core body are molded synchronously; the skeleton comprises the following materials in percentage by weight: 25 to 45 percent of cement, 25 to 45 percent of lightweight aggregate, 10 to 20 percent of basalt stone, 8 to 15 percent of mineral powder, 10 to 20 percent of plant fibers and 1 to 2 percent of admixture; the core body comprises the following materials in percentage by weight: 25 to 45 percent of cement, 25 to 45 percent of ultra-lightweight particles, 15 to 25 percent of mineral powder and 5 to 15 percent of foaming agent. The building block has the advantages that a skeleton body has high toughness, and is not easy to crack or generate microcracks; the core body is made of a lightweight heat insulation material, so that the specific gravity of the overall building block is reduced, and a heat insulation effect is enhanced; therefore, the overall weight of a built wall body is light, and the heat insulation performance is high.
