Exflor brings to you Autoclaved Aerated Concrete (AAC Blocks). Made from environment friendly raw materials, it is an ideal building material for use in today's times. It is an economical, sustainable, solid block that provides thermal & acoustic insulation as well as fire & termite resistance. AAC is available in a variety of forms, ranging from wall and roof panels to blocks & lintels. These blocks only look porous. Being a cellular structure, it actually blocks the capillary action, so water does not percolate unlike traditional blocks.
These blocks significantly outperform traditional bricks, fly ash bricks, conventional concrete blocks or poured concrete. Consistency in quality and colour can be obtained and exterior walls can be covered with a single exterior plaster cladding - enought to fight the exposure to physical damage, dirt and water.
- Autoclaved Aerated Concrete (AAC) blocks are made using Portland cement which is mixed with quartz (silica / PFA), water and an aeration agent and poured into a mould.
- The reaction between aeration agent & concrete causes millions of microscopic bubbles to form, expanding the concrete. That gives the block its unique properties.
- These blocks are then cut to size and formed by steam – curing in a pressurized chamber (autoclave). The result is a non organic, non toxic, airtight material that can be used for construction of walls.
