Fly ash bricks are made by combining water, quarry dust/river sand, cement, fly ash, and stone aggregates except 6mm, when the cement content is often substituted with 10% to 20% fly ash. They’re considered good and cheap building materials including Class C, ash, and water.

Here we’ll study ash bricks, properties of fly ash bricks & far more.

Introduction to fly ash bricks:

Hydraulic pressure devices produce ecologically beneficial fly ash bricks. They are 28 percent lighter than standard clay bricks and have a compressive strength of more than 40 MPA.

They are inexpensive and eliminate the necessity for plaster; it can reduce high construction costs and erosion.

Properties of fly ash bricks:

Appearance: The bricks have a satisfying cement color, which is uniform in shade and smooth, but doesn’t require plastering for building works.

Thermal conductivity: they are doing not absorb heat and provides maximum light reflection.

Sound Insulation: It provides a suitable degree of sound insulation.

Fire and Vermin Resistance: They need good fire resistance; it’s no problem with vermin attacks.

Durability and moisture content: These blocks are highly durable; the absorption of water is 6–12%, which reduces the humidity of the walls.

Toxicity and Stability: When mixed with lime, fly ash turns into a non-toxic product thus has potential as an honest artifact.

Advantages of fly ash bricks:

  1. Fly ash bricks are light in weight, so suitable for multi-story buildings because of the height of the buildings increases, the strain, and strain on the inspiration and structure increase.
  2. Thanks to the lighter bricks, this stress and strain are decrease manifold.
  3. These bricks absorb less heat and that they are better than clay bricks, for the Indian climate.
  4. Thanks to the high strength, there’s practically no breakdown during transport and use.
  5. The leakage of water through bricks is reduced thanks to less water penetration.
  6. Gypsum plaster (plaster of Paris) is often directly applied to those bricks without a backing coat of lime plaster.
  7. These bricks don’t require soaking in water for twenty-four hours, a sprinkling of water before use is sufficient.
  8. Less mortar is required during construction, further, the operation of the machine requires less labor.
  9. The compressive strength is extremely high and that they are less porous.
  10. They absorb less water and save costs.
  11. Its environmentally friendly therefore allows your business to require a step towards sustainable development.
  12. No fossil fuels are required for the assembly of fly ash brick hence no emission of greenhouse gases.
  13. The assembly of clay brick damages the topsoil and prevents fly ash within the process of producing bricks, there’s no solid loss.
  14. Fly ash bricks are stronger, more uniform, and denser than clay bricks.
  15. Their mortar consumption is low; their dissipation is merely 1% against clay bricks which is around 10%.

Disadvantages of fly ash bricks:

  1. Poor quality often features a negative impact on concrete; it can increase permeability, thus damaging the building.
  2. Some fly ash bricks that originate during a power station are usually suitable for concrete thus it’s vital to use only high-quality fly ash to stop negative effects on the structure of the building.
  3. The strength of mechanical bonding is weak but is often corrected using marble waste.
  4. There’ll be more wear and tear within the range of size.
