Fly Ash Bricks Complete Guide With Benefits, Uses And Vs Red Bricks Comparison
Fly Ash Bricks Are One Of The Most Popular Modern Building Materials Used In Construction Today. Due To Their Strength, Uniform Shape And Environmental Benefits, Fly Ash Bricks Are Rapidly Replacing Traditional Clay Bricks In Residential And Commercial Projects.
In This Detailed Guide, You Will Learn What Fly Ash Bricks Are, How They Are Manufactured, Their Advantages And Disadvantages, Cost, And A Clear Comparison Of Fly Ash Bricks Vs Red Bricks.
What Are Fly Ash Bricks ?
Fly Ash Bricks Are Building Blocks Made From Fly Ash, Cement, Sand Or Stone Dust And Water. Fly Ash Is A By-Product Of Thermal Power Plants Produced During Coal Combustion.
Unlike Traditional Red Bricks, Fly Ash Bricks Are Not Kiln Burned. Instead, They Are Manufactured Using Hydraulic Pressure And Proper Curing.
Because They Use Industrial Waste Material, Fly Ash Bricks Are Considered Eco-Friendly And Sustainable.
How Fly Ash Bricks Are Manufactured
The Manufacturing Process Of Fly Ash Bricks Includes The Following Steps:
1. Material Mixing
Fly Ash Is Mixed With Cement, Sand And Water In Proper Proportion.
2. Compression
The Mixture Is Placed In Molds And Compressed Using A Hydraulic Press.
3. Curing
The Bricks Are Cured For 14–21 Days To Gain Strength.
This Process Ensures Uniform Size, Better Finish And High Strength.
Standard Size Of Fly Ash Bricks
Common Fly Ash Brick Sizes In India Include:
- 190 Mm × 90 Mm × 90 Mm
- 230 Mm × 110 Mm × 75 Mm
Their Uniform Size Helps Reduce Mortar Usage And Speeds Up Construction Work.
Advantages Of Fly Ash Bricks
Fly Ash Bricks Offer Multiple Construction Benefits.
1. High Strength
Fly Ash Bricks Have Higher Compressive Strength Compared To Red Bricks.
2. Smooth Finish
