• Abstract:

  Autoclaved cellular concrete, also known as autoclaved aerated concrete, is a lightweight precast concrete building material developed in Sweden in the late 1920’s. Presently used in more than 35 countries for over 60 years, this product can be used for all types of structures ranging from single-family housing to large industrial complexes. ACC can be manufactured in a variety of shapes and sizes, allowing for maximum flexibility and efficiency in construction. It is available in blocks, wall and roof panels with or without reinforcement, lintels, beams and tongue and groove jointed panels.
  ACC is unique from lightweight aggregate concrete and other types of concrete in that it is composed of millions of microscopic cells generated during the manufacturing process. Unlike most other concrete products, it is steam cured in a high pressure autoclave. The raw materials and the manufacturing process are also unique, resulting in a building material superior in characteristics to most of the building materials presently available in the United States.
