Fly ash bricks are an eco-friendly alternative to traditional clay bricks as they require less energy and emit fewer greenhouse gases during production. They also help in the proper disposal of fly ash, which is otherwise a waste material that pollutes the environment. The use of fly ash bricks in construction can also reduce the demand for clay bricks, thus preserving the natural resources and ecosystem. Fly ash bricks have a high compressive strength, which makes them durable and long-lasting. They are resistant to moisture, fire, and insects, making them an ideal building material for construction projects. Fly ash bricks come in various sizes and shapes, making them versatile and suitable for various construction needs. Overall, fly ash bricks are a sustainable and cost-effective solution for building construction.
Bricks made from industrial wastes like fly ash, cement, and sand/stone dust are known as fly ash bricks.
Fly ash bricks have a particularly appealing appearance because of their consistent size, appealing hue that resembles cement, and smooth polish.
Without first applying a baking coat of plaster, plaster of Paris (gypsum plaster) putty can be applied directly.
These bricks don't have any cracks, wrap-age, organic material, stones, or unattached lime nodules.
Flyash Bricks | Red Bricks |
---|---|
Density - Density of fly ash brick is 1700-1850 kg/m3. | Density of Red brick is 1600-1750 kg/m3. |
Water Absorption - absorb about 6-12% of water. | Absorb more than 15-25% of water. |
Compressive strength - Compressive strength might vary within 10-12 N/mm2 | Compressive strength might vary within 10.3 N/mm2 |
Effloresces - Effloresces is unlikely in the fly ash brick. | Effloresce is one of the major problems for red brick. |
Wastage - only 2% of breakage during transportation. | More than 10% of breakage during transportation. |
Consumption of Mortar - Use of fly ash brick reduces mortar consumption. | Use of red brick requires more mortar in compare to. |
Surface - No plaster is required as it gives smooth surface. | Plaster is required to obtain smooth surfaces. |
