Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave.
1. Autoclaved aerated concrete combines insulation and structural capability in one material for walls, floors, and roofs. Its light weight/cellular properties make it easy to cut, shave, and shape, accept nails and screws readily, and allow it to be routed to create chases for electrical conduits and smaller-diameter plumbing runs. This gives it design and construction flexibility, and the ability to make easy adjustments in the field. 1. Durability and dimensional stability. A cement-based...
Autoclaved Aerated Concrete (AAC) - This Old House
Some call Autoclaved Aerated Concrete (AAC) a near-perfect building material. Patented in 1924 by a Swedish architect, AAC is made of common ingredients: portland cement, lime, silica sand or fly ash, water and a dash of aluminum powder.
About AAC | Aircrete Europe | What is AAC (Autoclaved Aerated ...
AAC Composition. Autoclaved Aerated Concrete consists of the unique combination of Tobermorite 11A molecules and air pores. Tobermorite 11A is a molecule that, once created, cannot physically decompose through heat, rot, corrosion or other chemical process and thus is very durable.
Autoclaved Aerated Concrete (AAC): Will the U.S. Ever Lighten ...
Feb 01, 2012 · To read what manufacturers and distributors say about it, you'd think autoclaved aerated concrete (AAC) was some kind of new, space-age environmental miracle.. Although it certainly has some nifty properties, AAC isn't new and isn't miraculous--but it's certainly popular in Europe, and has been for decades; according to one source, it accounted for 60% of all new construction in Germany in 2006.
Autoclaved aerated concrete products and production | APEX
Autoclaved aerated concrete (AAC for short) is a green, energy-saving and prefabricated building material that has been active in the global market for more than 70 years. It is made from natural raw materials such as water, quartz sand tailings, lime, cement and a small amount of aluminum powder.
Autoclaved Aerated Concrete (AAC) Blocks Proudly made for the ...
In this product guide, we use the terms Leichtbric, Autoclaved Aerated Concrete (AAC) and Autoclaved Lightweight Concrete (ALC) interchangeably to define and describe the Product and its general specification.
Autoclaved aerated concrete does not contain any aggregate; all the main mix components are reactive, even milled sand where it is used. The sand, inert when used in dense concrete, behaves as a pozzolan in the autoclave due to the high temperature and pressure.
Autoclaved Concrete. Autoclaved aerated concrete (AAC), a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, mainly by chemical reactions within the mass during the liquid or plastic phase.
Autoclaved aerated concrete, or AAC, is concrete that has been manufactured to contain lots of closed air pockets. Lightweight and fairly energy efficient, it is produced by adding a foaming agent to concrete in a mould, then wire-cutting blocks or panels from the resulting ‘cake’ and ‘cooking’ them with steam (autoclaving).
Sep 03, 2020 · Abstract. Autoclaved aerated concrete (AAC),also known as autoclaved cellular concrete (AAC), autoclaved lightweight concrete (ALC), autoclaved concrete, cellular concrete, porous concrete, is a lightweight, precast, Foam concrete building material invented in the mid-1920s that simultaneously provides structure, insulation, and fire- and mould-resistance.

Autoclaved Aerated Concrete Production | Masa Group
The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step. Masa's aerated concrete installations are proven advanced technology processes, designed according to customers specific requirements. This approach allows complete solutions to ensure highly ...
Aerated concrete block, also referred to as autoclaved aerated concrete or AAC, is an innovative type of concrete containing around 80 percent air. These special concrete blocks have a number of advantages: They're strong, light and provide better sound and thermal insulation than conventional blocks.
Aerated Concrete - an overview | ScienceDirect Topics
Autoclaved aerated concrete block products are coded by name (code name ACB), strength grade, bulk density grade, specification, product class, and standard number. For example, the excellent autoclaved aerated concrete blocks with strength grade of A3.5, bulk density of B05, and specifications of 600 mm×200 mm×250 mm can be marked as: ACB ...
Autoclaved Aerated Concrete (AAC) AAC has been used in large scale projects such as residential housing, schools, hospitals, hospitality, retail development, industrial and governmental buildings. At approximately twenty percent (25%) the weight of normal concrete/cinder block, light-block is unmatched in versatility and buildability.
Autoclaved Aerated Concrete blocks (AAC Blocks), which are also commonly known as Aerated Lightweight Concrete blocks (ALC Blocks) are common masonry blocks used in construction of a wall. AAC is a lightweight material composed of silica sand, gypsum, lime and cement.
AAC, or Autoclaved Aerated Concrete is a type of concrete that contains 80% air. It’s made with fine aggregates, cement, and an expansion agent that works like yeast in bread dough. It creates air bubbles and allows the cement mixture to rise. When it’s cured, the material is then molded and cut into AAC blocks and panels.
