Aerated Concrete Block 6" x 8" x 24"
Areated Concrete Block 6" x 8" x 24"
AC block are extraordinarily lightweight, and enhanced by a design structure that provides superior energy efficiency, fire resistance and acoustical properties. Engineered by the Swedes in 1914, and further developed in 1923, AAC block are used all over the world in a variety of structures and climates. AAC is comprised of Portland cement, lime, water, aluminum and sand. After the sand is ground to a powder-like consistency, it is mixed with the other ingredients to form a slurry. The slurry is then poured into a mold. The resulting chemical reaction between the hydration products and the aluminum powder, creates air bubbles which cause the material to rise in the mold. After curing for 45 minutes, the material is cut into individual units with piano wire. These units are then steam-cured in a pressurized chamber (an autoclave) for 8-12 hours. The final product is non-organic, non-toxic and airtight. It is appropriate for use in non- or load-bearing interior or exterior walls. AAC is environmentally friendly and can be shaped to conform to any design and almost any detail. Size: 6" x 8" x 24"
