Composite light aggregate concrete porous self-heat-preservation brick

The utility model relates to a composite light aggregate concrete porous self-heat-preservation brick which comprises a right-angled hexahedral brick body, wherein a plurality of vertical blind holes with sealed tops are formed in the brick body; inner ribs are formed between the adjacent blind holes; the blind holes and the edges of the brick body form outer ribs; the blind holes are divided into rhombic holes and triangular holes according to the shape of the cross section; the rhombic holes are surrounded by the triangular holes according to the distribution rule of the rhombic holes; the light aggregate concrete brick body is arranged, and light aggregate is formed by pumice sand, waste polyphenylene granules and waste rubber granules. The composite light aggregate concrete porous self-heat-preservation brick is large in void rate, reasonable in structure, low in cost, light in weight, and excellent in heat preservation and thermal insulation properties, is particularly applicable to building wall bodies in cold regions, and can achieve the aims of integrated heat preservation structure, source conservation, building energy conservation and environmental protection.
