Autoclaved Aerated Concrete Additive
AAC
Autoclaved Aerated Concrete (AAC) technology was first developed in Scandinavia over 70 years ago and is now used widely all over the world. But what is its history and how did this revolutionary material later become known as 'Hebel'? Lightweight and environmentally friendly, AAC was perfected in the mid1920s by the Swedish architect and inventor Dr. Johan Axel Eriksson and soon gained rapid ...

What Is Autoclaved Aerated Concrete [ACC]
· Autoclaved aerated concrete is precast lightweight material that has more fire resistance and better thermal insulation.. The concrete has 70 to 80% air which is developed by aluminum the concrete is baked in Autoclaved which is one type of furnace. And that is the reason why it is called Autoclaved Aerated Concrete.

Autoclaved Aerated Concrete
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. In the factory where it is made, the material is molded and cut into precisely dimensioned units. Cured blocks or panels of autoclaved aerated concrete are joined with thin bed mortar ...

Influence of Gypsum Additive on the Formation of ...
The quality of the aerated concrete strongly depends on the chemical composition of the raw materials, as well as the process of the hydrothermal reaction during autoclaving. Due to the variable chemical composition of fly ashes, it is necessary to identify the effect of each ion on the formation of the microstructure of aerated concrete. This paper examines the process of formation of ...

· Gypsum is a very popular mineral additive used in autoclaved aerated concrete (AAC) technology. In many studies, tobermorite can be synthesized from calciumsiliehydrate (CSH) phase under hydrothermal conditions in the presence of gypsum, and its impact on the tobermorite content in the AAC blocks has been discussed. It has been found in a previous study that tobermorite can be ...

How is autoclaved aerated concrete (AAC) made?
Answer (1 of 2): To the best of my knowledge AAC was created by a French company, LaFarge. AAC is a unique product that you cannot make on your own. There are no additives that you can throw into the wet mix and make AAC. It is a totally separate product from concrete as we normally know it. It i...
