AAC introduction

• Autoclaved aerated concrete (AAC), also known as autoclaved cellular concrete (ACC) or autoclaved lightweight concrete (ALC), was invented in the mid-1920s by the Swedish architect and inventor Johan Axel Eriksson. It is a lightweight, precast building material that simultaneously provides structure, insulation, and fire and mold resistance. AAC products include blocks, wall panels, floor and roof panels, and lintels.
• It has been refined into a highly thermally insulating concrete-based material used for both internal and external construction. Besides AAC's insulating capability, one of its advantages in construction is its quick and easy installation, for the material can be routed, sanded, and cut to size on site using standard carbon steel bandsaws, hand saws, and drills.

AAC can be produced in

Characteristics and Application

•  It is make up flakes solvent water surface, it is high active and scatter, it is mainly used air -entrapping beton and air -entrapping brick .
•  AAC is particularly economical in large scale projects.
• AAC product has been widely used in industrial and civil construction.
• AAC product can be divided into AAC block and AAC plate.
• Autoclaved aerated concrete is used in the construction of dwellings and businesses.
• Autoclaved aerated concrete is used preferentially in external walls because of its outstanding insulation properties.
• Autoclaved aerated concrete is used in multi-storey construction up to a level of around 5 stories.
• Autoclaved aerated concrete can also be used for internal walls. Because the walls are so level, they can be finished with a very thin coat of plaster (3 – 5 mm). Use of adhesive considerably reduces dampness in the brickwork.
• Autoclaved aerated concrete has the advantage that it can be shaped with saws, files and rasps. It is nevertheless very stable and thus suitable for load-bearing and non-load-bearing elements like shelves.
• Because of its low weight, autoclaved aerated concrete enables the construction of a fireplace as an add-on after the initial loads have been calculated without leading to significant extra stress on ceilings with standard load-bearing properties.
• AAC can be used to quickly create kitchen surfaces. The advantage for the tenant is that such a kitchen can easily be removed without damage to the surroundings.

 Aluminium powder for concrete block

Characteristics and Application
