Problems solved by technology

[0002] Although ordinary red bricks can be used for load-bearing walls, they are strictly prohibited materials, and their thermal insulation is too poor to meet energy-saving requirements
Although ordinary concrete blocks can be used as structural materials for bulky walls, their bulk density is too high, and they are not insulated. They cannot meet the national energy-saving standards and cannot replace red bricks.
Although ordinary lightweight concrete hollow blocks can be used as enclosure and filling materials for frame structure walls, their strength is too low to bear loads, and they still cannot meet the national technical standards of 50%-60% energy saving compared with red bricks. It still can't replace red brick

Abstract

The invention discloses a light-quality high-strength hyper-insulating architectural block, which comprises the following parts: 20%-40% cement, 19%-25% coal slag, 12%-25% basalt, 5%-15% mineral slag and 6%-15% doped material, wherein the doped material is composed of 80%- 90% modifier material and 10%-20% composite additive; the modifier material is one or two or more composition of vermiculite, pumice, foam glass, pearlite or diatomite according to random proportion; the compound additive is composed of 2.3% sodium hexametaphosphate, 0.7% triethanolamine and residual calcium oxide or sodium sulphate or their composition according to certain proportion.

Description

(1) Technical field [0001] The invention relates to a building material, in particular to a lightweight, high-strength, super-insulation building block. (2) Background technology [0002] Although ordinary red bricks can be used for load-bearing walls, they are strictly prohibited materials, and their thermal insulation is too poor to meet the energy-saving requirements. Although ordinary concrete blocks can be used as structural materials for bulky walls, their bulk density is too high, and they are not insulated. They cannot meet the national energy-saving standards and cannot replace red bricks. Although ordinary lightweight concrete hollow blocks can be used as enclosure and filling materials for frame structure walls, their strength is too low to bear loads, and they still cannot meet the national technical standards of 50%-60% energy saving compared with red bricks. It still cannot replace red bricks. (3) Contents of the invention [0003] The object of the present...
