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.
Aerated autoclaved concrete aac blocks.
These special concrete blocks have a number of advantages.
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.
It has a density of 600kg m3 and is particularly lightweight.
3 different sizes of aac blocks.
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.
Forms include blocks wall panels floor and roof panels cladding panels and lintels.
Invented in the mid 1920s aac simultaneously provides structure insulation and fire and mold resistance.
Autoclaved aerated concrete is a lightweight precast foam concrete building material suitable for producing concrete masonry unit like 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.
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 or aac is concrete that has been manufactured to contain lots of closed air pockets.
Autoclaved aerated concrete masonry unit aac walls are energy efficient.
They re strong light and provide better sound and thermal insulation than conventional blocks.
Aerated concrete block also referred to as autoclaved aerated concrete or aac is an innovative type of concrete containing around 80 percent air.
Autoclaved aerated concrete aac is a type of precast concrete composed of natural raw materials.
Our aac range is produced as a block.
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.
Autoclaved aerated concrete aac is made with fine aggregates cement and an expansion agent that causes the fresh mixture to rise like bread dough.
In fact this type of concrete contains 80 percent air.
E crete a manufacturer of autoclaved aerated concrete block aac located in the southwestern u s.
