    2016-05-15  Autoclaved aerated concrete (AAC) is a lightweight cellular concrete. Recycling AAC in concrete or unbound applications may cause problems because of high amounts of leachable sulfate. This study evaluates the recycling of AAC demolition waste as a replacement of sand in floor screed.

  • Autoclaved aerated concrete YourHome

    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).

  • Application of recycled waste material for the production ...

    At these levels, the recycling of waste concrete is becoming increasingly important from a political and environmental perspective. Currently, a large part of the waste concrete is mechanically processed and recycled mainly in road construction. Only a small part is used as a secondary aggregate in the production of new concrete 16.

    AdvantagesSizesInstallation, Connections, and FinishesSustainability and Energy ConsiderationsManufacturing and Physical PropertiesAutoclaved Aerated Concrete1. 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. DuraSee more on cement.org
  • Aerated Concrete - an overview ScienceDirect Topics

    Autoclaved aerated concrete is a porous concrete used widely in several countries. The adhesive material of it is cement or lime powder, fly ash, mixed with fine sand or slag and water. In the meantime, the foaming agent is put into the liquid and numerous stable bubbles of diameter 1–2 mm are produced, and the uniform porosity is formed.
