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:
- 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.
- Thanks to the lighter bricks, this stress and strain are decrease manifold.
- These bricks absorb less heat and that they are better than clay bricks, for the Indian climate.
- Thanks to the high strength, there’s practically no breakdown during transport and use.
- The leakage of water through bricks is reduced thanks to less water penetration.
- Gypsum plaster (plaster of Paris) is often directly applied to those bricks without a backing coat of lime plaster.
- These bricks don’t require soaking in water for twenty-four hours, a sprinkling of water before use is sufficient.
- Less mortar is required during construction, further, the operation of the machine requires less labor.
- The compressive strength is extremely high and that they are less porous.
- They absorb less water and save costs.
- Its environmentally friendly therefore allows your business to require a step towards sustainable development.
- No fossil fuels are required for the assembly of fly ash brick hence no emission of greenhouse gases.
- The assembly of clay brick damages the topsoil and prevents fly ash within the process of producing bricks, there’s no solid loss.
- Fly ash bricks are stronger, more uniform, and denser than clay bricks.
- Their mortar consumption is low; their dissipation is merely 1% against clay bricks which is around 10%.
Disadvantages of fly ash bricks:
- Poor quality often features a negative impact on concrete; it can increase permeability, thus damaging the building.
- 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.
- The strength of mechanical bonding is weak but is often corrected using marble waste.
- There’ll be more wear and tear within the range of size.
