Autoclaved aerated concrete aac is made with fine aggregates cement and an expansion agent that causes the fresh mixture to rise like bread dough.
Aerated autoclaved concrete aac blocks.
It was first developed in sweden in the 1920s when an architect first combined the conventional concrete mixture of cement lime water and sand with a small amount of aluminum powder.
Invented in the mid 1920s aac simultaneously provides structure insulation and fire and mold resistance.
3 different sizes of aac blocks.
An 8 aac block wall has a steady state r value of approximately 10 and a higher total equivalent performance r value when factoring dynamic benefit for massive systems dbms or thermal mass.
These special concrete blocks have a number of advantages.
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.
They re strong light and provide better sound and thermal insulation than conventional blocks.
In the factory where it is made the material is molded and cut into precisely dimensioned units.
Autoclaved aerated concrete masonry unit aac walls are energy efficient.
Autoclaved aerated cement blocks aac blocks properties and advantages home building technology guide building autoclaved aerated concrete is an eco friendly and certified green building material which is lightweight load bearing high insulating durable building blocks and 3 times lighter when compared to red bricks.
Aac is an energy efficient fire and mold resistant sustainable green building material.
Forms include blocks wall panels floor and roof panels cladding panels and lintels.
Composed of quartz sand calcined gypsum lime cement water and aluminum powder aac products are cured under heat and pressure in an autoclave.
Autoclaved aerated concrete is a lightweight precast foam concrete building material suitable for producing concrete masonry unit like blocks.
It has a density of 600kg m3 and is particularly lightweight.
Autoclaved aerated concrete aac is made from sand lime cement water and aluminium powder acting as a foaming agent to form homogenous cellular structure known as calcium silicate hydrate.
Our aac range is produced as a block.
Autoclaved aerated concrete aac is a type of precast concrete composed of natural raw materials.
In fact this type of concrete contains 80 percent air.
