AAC/ALC BONA Block Aerated Block-Aac Block
Autoclaved Lightweight/Aerated Concrete block,is shorted for AAC/ ALC block, using silica sand,cement and lime as the raw material,aluminium power as the foaming agent,after high tempreature, high pressure steam raised. Easy to cut and install,is widely used to construct internal and external wall. ALC block is also one kind of self-heat preservation materials,makes the external wall an excellent thermal insulation system.
Domestic first-class scientific research team, set scientific research factory as one.
Specifications:
Lightweight: Porosity achieves 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, and reduce the cost of integrated buildings.
Fireproof: Most of the major raw materials are inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach 245 minutes of fire resistance, and 300mm thick up the wall can reach 520 minutes of fire resistance.
Sound insulation: Due to a unique porous structure, it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 dB.
Insulation: The material inside has a large number of pores and is porous, which has a good thermal insulation property. The Thermal conductivity is 0.11-0.16W/MK, like 1/4-1/5 of brick. Typically, the insulation effect of a 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly with paste tiles.
Anti-seismic: The same building structure, improves the two seismic than the brick level.
Green: Manufacturing, and transportation, all use the process of pollution, to protect arable land, and save energy, this is one kind of green building material.
Durability: material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25% and remained stable after ten years.
Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
Economies: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
