Product Description

 

AAC block (autoclaved aerated concrete block)  is also known as autoclaved cellular concrete (ACC) or autoclaved lightweight concrete (ALC).  Aerated concrete were created by Hofman from Czech Republic in 1889 and were improved by  J.A.Eriksson in 1923.AAC block is a unique and excellent type of construction material with cement, lime, silica sand and foaming materials as the main raw materials. The chemical reactiondue to the aluminum paste provides AAC its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials. The porous crystalline AAC block is produced through high temperature, high pressure and steaming process and has excellent performance in fire resistance, anti-seismic, and warm keeping.

  It is called AAC for those small  pores inside after foaming. The advantageswhich make it one of the most popular wall materials are as follows:

 

  Lightweight :  density of AAC block is 400-700kg/m3,1/3 of solid clay blocks, 1/5 of common concrete blocks.

Fire proof : main materials of AAC blocks are inorganic. it has features of keeping temperature, resisting fire and

releasing no harmful gas.

 

  Sound insulation noise reduction :with distinctive large quantities of pores inside, AAC blocks have great

sound insulation, its sound insulation index of 100mm thick can achieve 40.8db

 

Good heat preservation,energy saving : with a large number of pores inside, AAC blocks have good heat preservation

 

♥  Reducing project cost and Convenient construction : surface of AAC blocks are smooth, it needn't plastering , lots of decoration costs will be saved. It can be sawed, cut, drilled freely and bound with other building materials which is favorable for building

 

Anti-seismic :AAC blocks have light weight, so it have low inertia and good performance on anti-seismic

 

  Environmental protection :slag, flyash, mine waste and other industrial wastes can be used as raw material of ALC panel,which is friendly to environment

AAC blocks are superior lightweight new wall materials which can save energy, utilize industrial solid wastes and protect environment. It can not only replace burnt solid blocks, but also do as thermal insulation materials. AAC is the most economic and simplest way to realize building energy conservation.
