Unusual bricks called fly ash bricks are created using cement, sand or stone dust, and industrial by-products like fly ash. It’s uniform in shape & size.
Currently, these kinds of bricks are more widely used than clay ones all over the world.
Fly ash bricks are used as a substitute for burned clay bricks in construction projects.
A fly ash brick may endure more than 100 freeze-thaw cycles if it is crushed at 28 MPa, treated for 24 hours in a steam bath at 66 °C, and then strengthened using an air entrainment solution.
Due to the presence of an adequate quantity of calcium oxide in class C fly ash, these bricks are referred to as “self-cementing”.
Fly ash bricks typically cost 30% or less than ordinary clay bricks, consume less energy, and release less mercury into the environment.
Fly ash bricks are created using hydraulic pressure machines that are ecologically friendly.
In comparison to standard clay bricks, these bricks are 28% lighter and possess a compressive strength greater than 40 MPa.
Fly Ash Bricks Raw Materials
- Fly ash – main component
- Stone or sand dust – used as a fine aggregate
- Lime – source of calcium carbonate
- Gypsum – used to make the bricks’ shape more precisely
- Cement – strengthens bonds and improves adhesion
Fly Ash brick Types
- Fly Ash Brick
- AAC Blocks
- Fly Ash Interlock Bricks
- CCL Bricks
- Class F, typically produced by burning bituminous coal or anthracite
- Class C, mainly produced by burning lignite or sub bituminous coal
Fly Ash Brick Applications
Bricks made from fly ash are often used in small to medium-sized structures and small load-bearing buildings.
They are used in place of conventional bricks made of clay, and they have better qualities.
Used in factories, power stations, offices, warehouses, multi-storey or high-rise projects, and home construction.
Benefits of Fly Ash Bricks
Compared to conventional bricks, these bricks are lighter, which makes them perfect for tall buildings.
Red bricks are more expensive to produce, whereas fly-ash bricks are less expensive.
These bricks offer greater thermal insulation by absorbing less heat when compared to other materials.
Since there are no fossil fuels used in the production of fly ash bricks, no emissions of greenhouse gases occur.
You can go closer to green as well as sustainable development because it is good for the environment.
It is sufficient to lightly mist these bricks with water prior to usage rather than soak them for 24 hours.
Fly Ash bricks are more durable, uniform, and dense when compared to clay bricks.
Bricks made with fly ash become less absorbent and have high strength during compression.
Now, we talk about the most important thing i.e. Drawbacks of Fly Ash Bricks
Not every kind of fly ash is suitable for building; some types are produced at power plants and are often equivalent to cement, while others could need purification.
To prevent damaging effects on the building, it is relatively crucial to employ only top-quality fly ash.
If bricks aren’t correctly prepared, they won’t be strong enough to be used in construction and won’t work.
Concrete suffers from the effects of low-quality bricks.
When the framework is damaged, it might cause porosity to increase.
Because of the brick’s smooth surface, there is less bonding with the cement.
Limitation on size, bricks only in modular sizes can be produced.
Larger bricks will break more frequently.
Fly Ash bricks will absorb more heat and inject the heat inside the building during night this don’t happen will Mud Interlock Bricks
There may be damages in transits.
Consult with Dolfix Construction Expert Team to supply and construct buildings with widely used Interlock bricks which are better than all other bricks in the market for your project.
