Benefits of Fly Ash Bricks Machine
Fly ash refers to the ash produced during the combustion of coal. It is the fine powder formed from the
mineral matter in coal, consisting of the non-combustible matter in coal plus a small amount of carbon
that remains from incomplete combustion. Fly ash is being accumulated as waste material in large
quantities near thermal power plants. As the power requirements of the country go up, the amount of
waste produced will also increase enormously creating problems for its safe disposal due to a lack of
adequate disposal facilities. Its use in the manufacture of bricks will be helpful in its disposal and also help in
controlling pollution. It is supplied free of cost to entrepreneurs
Fly Ash bricks are made of fly ash, lime, gypsum and sand. The raw materials are blended in desired
proportions in a Pan mixer for 4-5 minutes and compressed. They undergo curing for a minimum of 14
days and are then air dried for 7 days. Strength of these bricks can be engineered by varying the
compositions. These can be extensively used in all building constructional activities similar to that of
common burnt clay bricks. The fly ash bricks are comparatively lighter in weight and stronger than
common clay.
Benefits:
- High compressive strength.
- Low water absorption.
- Dimensional accuracy through uniform shape.
- High strength to weight ratio.
- No emission of greenhouse gases during production.
- Zero efflorescence.
- Consume less mortar in construction
