What are fly ash bricks?

Before getting a hang of what fly ash bricks are, one must, first of all, understand its major component: fly ash.

Fly ash is the glassy looking residue formed after the combustion of pulverized coal in electrical power generation plants and thermal power stations powered by coal. They form when mineral impurities in the coal fuse together and flow out of the combustion chamber alongside exhaust gases. Formerly, it was often thrown away as waste but presently, using it is considered a huge benefit to the ecosystem instead of accumulating it at dumpsites. In recent times, fly ash has become a great additive to Portland cement. As a matter of fact, such cement has been discovered to develop great properties when fly ash is added. The properties include heat evolution, aggregate reaction, permeability, strength, easy workability, reduction in hydration temperature, etc.

Fly has a wide range of applications such as PCC, flowable fills, asphalt filler, concrete etc.

Fly ash serves as good additives to cement and water. They greatly improve the workability of concrete.

According to reports, 61 million tonnes of fly ash are generated each year. What this means, is that it is cheap and easy to obtain.

On the other hand, fly ash bricks are simply bricks in which fly ash has been used as an admixture. They have a strong correlation in colour, with concrete bricks.

The addition Of fly ash to concrete confers several beneficial properties which will be covered below.

What are the advantages of fly ash bricks?

Fly as bricks have several advantages both to the building itself and the environment in general. Some of them are:

• Fly ash bricks are far lighter than conventional clay bricks but still rank higher in strength per weight. Their weight makes them suitable for high rise buildings.

Although they are lighter, they still possess a high strength to weight ratio.

• Fly ash bricks help to rid the environment of the environmental pollutant (fly ash). Before the advent of fly ash bricks, steam and electric generation plants running on coal, had to dump fly ash in dumpsites. Hence, the environment suffered from it. Since a use for fly ash bricks has been found, this practice has been reduced greatly.

Another ecological gain of using fly ash, is associated with the soil. During production of clay bricks, a massive amount of soil is excavated. In recent years, many environmental conservationists have complained about the harm it causes to the environment.

• Money to be spent on mortar when using fly ash bricks is reduced. Even with the low amount of mortar consumed, fly ash bricks are still stronger than your regular clay bricks.
• Fly ash bricks have a very high compressive strength. As a result, fly ash bricks are less permeable. Hence, water does not seep through.
• Frost resistant. This is very important especially in areas that experience snow falls.

What are the advantages of fly ash bricks?

Fly ash bricks are made in three important steps: mixing, pressing and curing.

• Mixing

The raw materials – class C fly ash and sand – are fed into the materials hopper. After that, the conveyor belt moves the raw materials to the mixer where cement and water are then added. The raw materials are allowed to mix thoroughly for five minutes before moving to the next process.

It’s important to get the proportions and mixing time correctly as this will later determine the quality of the bricks.

• Pressing

The mixture is fed into the mould where high hydraulic pressure presses it into whatever design, shape or size taken by the mould. Vibrations are also used to shake the mould.

• Curing

The bricks are kept in the curing section for 15 to 18 days and watered twice daily to increase its density.
