Product Description

AAC :
1. Introduction
Aerated concrete block (light block ) is the light and porous building material. It has light weight, keeping temperature, cannot burn and other advantages. It can be made into many kinds of blocks(for example: 600× 200× 100, 80× 80× 180, 240× 115× 53, 600× 200× 125), they could be used industry building and common building. They are more and more popular in the world. In the future, they will replace the Clay brick completely.
2. Areated concrete common conception:
Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3, 600kg/m3, 700kg/m3. It has not the big grain, main use silicon material (for example: Coal ash, sand, stone dust and others ), through making the material small for example sand, they can be used directly if has enough degree of small (for example coal ash. Mixing calcium material lime cement water to a special slop, then add the aluminum dust and the additive. Make the aluminum dust and the special slop have a Chemical reflect. Then produce Hydrogen to make the concrete slop to expanding or swell, foam. Next, put them into the curing room to concreting cutting steaming curing, last, there will become the light brick, the porous rate is 70-80%.
3.Advantages:
1.Lightweight: Porosity achieve 70% to 85%, volume density is generally 500-900kg/m3, as 1/5 of general concrete brick,the 1/4of clay brick, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building,moreover,prolong building's life.
2.Fireproof: Most of the major raw materials is 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 100 mm walls can reach to 4 hours fire resistance, 300mm thick up wall can reach to 9 hours fire resistance.
3.Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 100mm thick wall up to 41 db.
4.Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
5.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 paste tiles.
6.Anti-seismic: The same building structure, improve the two seismic than the brick level.
7.Green: Manufacturing, transportation, all use the process of non-pollution, to protect arable land, saving energy, is one kind of a green building material.
8.Durability: material strength is stable, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable even after ten years.
9.High workability: 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.
10.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.
