Description


Lightweight  fireclay brick has the characteristics of no deformation, non-toxic and odorless, safe and convenient construction. It is an ideal material for wall insulation, heat insulation and compartment; it can not only increase the temperature, shorten the heating time, but also reduce the fuel consumption. And it has good sound insulation and sound absorption effect, which is the best choice for energy-saving and environmental protection equipment.

Features

1. Light weight: the dry capacity of lightweight brick is only 500-700Kg/m*3, which is 1/4 of that of ordinary concrete
, 1/3 of clay, 1/2 of hollow block, because its bulk density is smaller than that of water, commonly known as aerated concrete floating on the water surface, the use of this product in construction can reduce the self-weight of the building and greatly reduce the weight of the building. comprehensive cost.
2. Heat preservation and heat insulation: During the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the effect of heat preservation and heat insulation, so that the thermal conductivity of aerated concrete is 0.11- 0.16W/MK. The thermal insulation effect is 5 times that of clay bricks and 10 times that of ordinary concrete.
3. Sound absorption and sound insulation: The porous structure of air-entrained concrete makes it have good sound absorption and sound insulation performance, which can create a high air-tight indoor space for you. Provide you with a quiet and comfortable living environment.
4. Small shrinkage value: due to the use of high-quality river sand and pulverized coal as siliceous materials, the shrinkage value is only 0.1--0.5mm/m, and the small shrinkage value of high-quality materials ensures that your wall will not crack.
5. Impermeability: The pore structure of this product makes it poor in capillary action, and it absorbs water slowly and conducts moisture slowly. The time required for the same volume of water to absorb water to saturation is 5 times that of clay bricks.
6. Environmental protection: The manufacturing, transportation and use process are pollution-free, energy-saving and consumption-reducing, and are green and environmentally-friendly building materials.
7. Earthquake resistance: The same building structure uses lightweight bricks to improve the earthquake resistance level than clay bricks.
8. Durability: The long-term strength of air-entrained concrete is stable. After one year of exposure to the atmosphere of the specimen, the strength has increased by 25%, and it remains stable after ten years.
9. Processability: light weight, various sizes, easy to nail, drill, chop, saw, plan and lay pipelines, and use expansion pipes on the wall, which can directly fix hanging cabinets, air conditioners, range hoods, etc., for you The installation of water and electricity, home decoration brings convenience.
10. Refractory: The degree of refractoriness is degree, which is a first-class refractory material. The fire resistance of 100mm thick blocks can reach 225 minutes, and the fire resistance of 200mm thick blocks can reach 480 minutes.
