Fly Ash Brick Plant: Producing the Best Bricks
The fly ash brick plant is a hydraulically operated plant used to manufacture a building material called fly ash brick. Controlled through a modern electronic interface, a fly ash brick plant generally consists of various components such as a brick making machine, pan mixer, conveyor and sometimes even pallet trucks. The advantage of fly ash brick plants is that these produce bricks that have a high fire insulation, high stress tolerance, which allow considerably lesser seepage of water and have a uniform size.
The plants compress a mixture of water and fly ash at 28 MPa, then cure it for 24 hours inside a 66 degrees Celsius steam bath. Afterwards, the mixture is toughened with an air entrainment agent. Compared to clay bricks, these fly ash bricks are lighter in weight and can endure more than 100 freeze-thaw cycles. Other properties of the bricks are a compressive strength of 55 to 100 kgf/cm square and a water absorption rate of 10 to 15 percent. Due to these reasons, fly ash bricks are extensively being used for all major construction purposes these days.
Raw Materials Used by Fly Ash Brick Plants to Make Fly Ash Bricks are:
Land requirement for fly ash brick plant
Generally the land required for fly ash brick plant varies from 0.5 to 1 hectare. Also, unlike a red brick unit the plant is mainly confined to a single place. Simply put, any fly ash brick making plant can be operational on a wide type of land that is preferably flat.
Salient Features of Fly Ash Brick Plants
Minimal waste materials – Unlike clay bricks, the manufacture of fly ash bricks produces negligible solid waste. Moreover, waste materials arising from breakage of the bricks during manufacturing process are recycled in the process itself
Noise – The noise levels of fly ash brick plants are minimal
Less air pollution – A fly ash brick plant itself doesn't produce too much greenhouse gases. The main green house gas around a fly ash brick plant's vicinity is carbon dioxide emanating from the operation of diesel generators for power if required and vehicular movement
Minimum effect on terrestrial ecology and minimal loss of of agricultural land
No heat emission
