ACC Blocks

ACC Blocks :


Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave.

Advantages of AAC Blocks
   •Fire Resistant
   •Pest Resistan
   •Earthquake Resistant
   •Sound Proof
   •Faster Construction
   •Long Lasting
   •High Compressive Strength
   •Cost Saving
