Ten properties of light brick

1, capacity light: light brick its dry capacity is only 500-700Kg/m*3, is ordinary concrete 1/4, clay 1/3, hollow block 1/2, due to its bulk density than water, commonly known as floating on the surface of aerated concrete, the use of this product in the building, can reduce the weight of buildings, greatly reduce the overall cost of building.

2, heat preservation and heat insulation: because of the air entrained concrete in the manufacturing process, the internal form a tiny hole, these holes in the material to form the air layer, greatly improve the insulation effect, so that the thermal conductivity of aerated concrete is 0.11-0.16W/MK. Heat preservation effect is 5 times of clay brick, 10 times of ordinary concrete.

3, sound absorption, sound insulation: aerated concrete porous structure made it a good sound absorption, sound insulation performance, you can create a high air tightness of indoor space. Provide a quiet and comfortable living environment.

4, small shrinkage: due to the use of high quality river sand and powder coal as a silicon material, the shrinkage value is only 0.1–0.5mm/m, the value of the small shrinkage of fine material to ensure that your wall will not crack.

5, non permeability: the product of the pore structure, so that the capillary effect is poor, water absorption of wet slow, with the volume of water to the saturated time is 5 times the clay firebrick.

6, environmental protection: manufacturing, transportation, use of the process without pollution, protection of arable land, energy saving, is a green building materials.

7, earthquake: the same building structure using light brick than the clay brick to improve the seismic level.

8, durability: aerated concrete long-term strength and stability, in the test piece of atmospheric exposure to a year after the test, the intensity increased by ten, 25% years after still remain stable.

9 and processing: This product is light weight. Size specifications are various, convenient nail, drilling, cutting, sawing, planning engrave the laying of pipelines and on the wall use expansion tube can directly fixed condole cabinet, air conditioning, Shan machines and other, to your water and electricity installation, home decoration convenience.

Advantages of light refractory brick

Light brick is generally refers to the foam bricks, the normal indoor partitions are used thisbrick, will not increase the floor load, while the sound insulation effect is good! Strength of products selected high-quality tabular corundum, mullite as aggregate, sillimanite compound as
a substrate, added special additive and a small amount of rare earth oxide mixing, the high pressure shaping and high temperature firing. Fireclay and high alumina high strength bead brick, low iron mullite and High strength aluminum chemosphere brick, diatomite insulating refractory brick ordinary lightweight insulating refractory brick production material.

Advantages of light brick:

1, the economy: can reduce the cost of the foundation; reduce the frame of the section, save reinforced concrete can significantly save the comprehensive cost of building. Design and use of
light brick than the use of solid clay brick, the overall cost can be reduced by more than 5%.

2, practical: the use of light brick can increase the use of area, but due to the aerated concrete insulation, good heat preservation effect, in the hot summer, the indoor temperature than the use of solid clay brick low 2-3 C, use air conditioning, and reduce power consumption.

3, construction: light brick has good workability, the construction is convenient and simple, because the firebrick is big, the quality is light, can reduce labor intensity, improve construction efficiency, shorten the construction period.
