Fly Ash Bricks and Comparison with Clay Bricks – Composition, Manufacture
The fly ash bricks are utilized more and more nowadays in brick masonry constructions. The fly ash bricks are high in quality and made using advance technologies. It's used as replacement for clay bricks and it's far better than it.

By means of fly ash brick compared to ordinary clay bricks possess many advantages. The most important advantage of using fly ash bricks is how that we could save natural resources and protect surroundings.
Composition of Fly Ash Brick
• Fly ash
• Cement
• Sand
• Water
Fly Ash Comes From
India's 72% energy plants are coal established and these plants produce 40 million bunch fly ash each year. The fly ash comprises Co2 that's generated from renewable power plants and businesses which used coal as fuel and sparks smoke and ash and out of it that the fly ash is created. The plants and businesses utilize cyclone converters to fly ash and this fly ash is used as raw material for producing fly ash bricks.
The Pollution Caused by Fly Ash
The fly ash cause ...
... more ecological issues include water, air and also property. It required appropriate direction to control pollution brought on by fly ash and there for usage fly ash to create several products and preserve the environment.
Making of Fly Ash Brick
The fly ash Brick is a gradual setting pozzalona concrete mix. The practice is nearly identical to earn cement in which the clay and limestone are burnt with irrigation and gypsum and mixed.
In fly ash when the grated lime powder, gypsum are blended in a bowl, the mix starting turns gradually in pozzalona cement.
The mix Is pressed in reduced pressure in reduced moisture in hydraulic system and the system is especially designed to offer high pressure at slow speed and the strain is 350kg/square inch.
The required Fly ash bricks.
Advantages of Fly Ash Brick
The emission of greenhouse gases is growing more and more today and the Co2 is major one.
In India the CO2 emissions from cement industry is ninety million tons plus twenty eight tons from clay brick manufacturing. As per present statics for generating one million brick required 200 tons of coal and this coal emits around 270 tons of CO2 from the air.
The Fly Ash Brick production is totally emission free and the production procedure is Qualified under Clean Development Mechanism (CDM).
Comparison between Clay Bricks and Fly Ash Bricks
Properties Red Brick/Clay Brick Fly Ash Brick Remark
Density 1600-1700 kg/m3 1700-1850 kg/m3 Higher Load Bearing
Compressive Strength 30-35 kg/cm2 90-100 kg/cm2 Higher Load Bearing
Absorption 15-25% 10-14% Less dampness
Dimensional Stability Very low tolerance High tolerance Saving in mortar up to 25%
Wastage during transit Up to 10% Less than 2% Saving cost up to 8%
Plastering Thickness vary on both sides of wall Even on both sides Saving in plaster up to 15%
