Other Details:

 

  • We deal with AAC BLOCK (Autoclaved Aerated Concrete), is also known as autoclaved cellular concrete (ACC), these are Thermalite Blocks developed in the mid-1920s in Sweden. These are light-weight and pre-cast building materials that simultaneously provide structure, insulation, and fire and mold resistance. One of the major advantage of AAC over other cementitious construction materials is its lower impact on environment. It has no efflorescence emission (white salt appearance) at large.
  • It is highly thermal insulating product used for both internal and external construction. It is easy and quick to install since the material can be routed, sanded, and cut to size on site using standard carbon steel band saws, hand saws, and drills. Major application of AAC products include light weight partition walls, protection of steel structure and lintels. The common sizes are (LxWxH) 600mm x 200mm x 100mm.
  • Autoclaved aerated concrete is a versatile lightweight construction material and usually used as blocks. Compared with normal (i.e.: "dense" concrete) air Crete has a low density and excellent insulation properties.The low density is achieved by the formation of air voids to produce a cellular structure. These voids are typically 1mm - 5mm across and give the material its characteristic appearance. Blocks typically have strengths ranging from 3-9 Nmm-2 (when tested in accordance with BS EN 771-1:2000).Densities range from about 460 to 750 kg m-3; for comparison, medium density concrete blocks have a typical density range of 1350-1500 kg m-3 and dense concrete blocks a range of 2300-2500 kg m-3.
  • The essence of air Crete production is that lime from the cement and lime in the mix reacts with silica to form 1.1 nm tobermorite. During the green stage, the cement is hydrating at normal temperatures and the hydration products are initially similar to those in dense concrete - C-S-H, CH and ettringite and/or mono sulphate. After autoclaving, tobermorite is normally the principal final reaction product due to the high temperature and pressure.
  • Small amounts of other hydrated phases will also be present in the final product. Additionally, hydrated phases form in the autoclave as intermediate products, principally C-S-H(I). This is a more crystalline form of calcium silicate hydrate than occurs in dense concrete; it can have a ratio of calcium to silicon of (0.8< Ca/Si <1.5) but 0.8 to 1.0 is desirable as this ratio facilitates the formation of 1.1 nm tobermorite.
  • Autoclaved aerated concrete blocks are excellent thermal insulators and are typically used to form the inner leaf of a cavity wall. They are also used in the outer leaf, when they are usually rendered, and in foundations. It is possible to construct virtually an entire house from autoclaved aerated concrete, including walls, floors - using reinforced air Crete beams, ceilings and the roof. Aerated concrete blocks are ideal for all kind of structures such as schools, hospitals, hotels, offices, independent housing and apartments.
