New York City Approves the Use of Autoclaved Aerated Concrete

New York, NY - March 23, 2001 - Autoclaved Aerated Concrete Systems, Inc. is proud to announce that New York City has approved the use of Autoclaved Aerated Concrete (AAC) blocks and panels in building construction projects. "This approval opens a tremendous market for Autoclaved Aerated Concrete, and allows construction in New York City to benefit from the many attributes of AAC." explained Keith Itzler, President of AACS, Inc.

"AAC has emerged as the ultimate building material, Its unique combination of superior strength, light weight and workability makes the construction process much more efficient, saving both time and labor costs," said Itzler. "AAC provides long-term benefits that maximize occupant comfort and increase functionality for any type of building."

AAC has been used for close to seventy years and in twenty-eight countries around the world, including the United States. AAC is a single component building material that combines the most advantageous properties of reinforced pre-cast concrete, masonry and timber providing a high degree of versatility to Owners, Builders and Architects in building design.

Autoclaved Aerated Concrete is a mixture of portland cement, quicklime, sand, water and aluminum powder. The chemical interaction of these "aerated" natural materials creates a porous, closed cell masonry material, which reaches full strength in less than twenty-four hours and is roughly one-third the weight of stone concrete. AAC is manufactured using all natural resources with no harmful emissions or toxic chemicals. AAC products are completely environmentally compatible and qualify as a "green" building material.
