Characteristics of aerated concrete plate

ALC is the abbreviation of Lightweight Concrete (Autoclaved), which is a kind of high performance vapor pressure aerated concrete (ALC). ALC board is to fly ash or silica sand, cement and lime as main raw material, after high-pressure steam curing of multi hole concrete sheet forming (containing after treatment of reinforcements enhanced). ALC board can be used as wall material, but also can be used as a new type of building materials with superior performance. ALC board was first appeared in Europe, Japan, Europe and other regions have more than 40 years of production, application history. The current production technology and production equipment mainly comes from domestic manufacturers in Japan and Germany

1 light weight of its dry weight is only 0.5, is a concrete 1/5, hollow brick 1/3, known as the floating on the surface of the concrete. Calculation of Capacity Construction: fand 650KG/m.

2 the thermal conductivity of NALC is K 0.11W/m, which is ten times that of ordinary concrete, and the insulation property of ALC 125mm is equivalent to 370mm clay brick wall, which is a building material with good thermal insulation properties.

3 refractory NALC series of inorganic non combustible material, good thermal stability, heat transfer slow, has a good fire resistance, 100mm thickness of the plate to reach 4 hours or more refractory. 50mm thick steel beam fire resistance limit of 3 hours, 50mm thick steel beam fire resistance limit of 4 hours, are more than a grade refractory.

4 sound insulation NALC products internal microstructure is by mutual non-uniform connectivity of tiny pores, with dual properties of sound insulation and sound absorption. 100mmACC in the average sound transmission loss is 40.8dB; double 5mm thick putty average sound transmission loss is 45dB.

5 bearing NALC board as the retaining structure of the retaining structure, with the characteristics of light and high strength, the internal structure of the plate with the design requirements of reinforced mesh, can withstand the corresponding wind load, snow load and dynamic load.

6 the seismic performance of NALC plate is light, and its scientific and reasonable installation method, which makes the board has good follow up, and the seismic performance test, and the low cycle repeated test of the steel structure residential system, both in the Tongji University and Southeast University.
