Extended data:
Light brick or light block: refers to the brick or block with small volume density and certain compressive strength. Such as: aerated concrete block (also known as aerated block and Yitong brick).
Scope of application: suitable for hotel partition walls, KTV boxes of entertainment clubs, office partitions, etc.
Main functions:
1 light: the absolute dry bulk density is 500-600 kg/m3, which is 1/4 for ordinary concrete, 1/3 for clay brick and 1/2 for hollow brick, which is similar to wood and can float in water. It can reduce the self-weight of the building and greatly reduce the comprehensive cost of the building.
Fire protection: the fire resistance rating is 700 degrees, which is a class A incombustible refractory. /kloc-the fire-resistant time of 0/00 mm thick wall reaches 225 minutes, and that of 200mm thick wall reaches 480 minutes.
Sound insulation: due to its porous structure, it has good sound absorption and sound insulation performance, and the wall with a thickness of 10mm can reach 4 1 dB.
