Fly ash bricks are generally considered more durable than normal or red bricks. Here’s why:
1. Higher Compressive Strength: Fly ash bricks typically have a higher compressive strength than red bricks, making them a more durable option.
2. Uniform and Smooth Texture: Unlike red bricks, fly ash bricks have a uniform, smooth texture on both sides, which means they require less plastering during construction. This can contribute to their overall durability.
3. Better Insulation Properties: Fly ash bricks are better insulators compared to red bricks. This can result in energy savings in buildings where these bricks are used.
4. Water Resistance: Fly ash bricks are more resistant to water seepage compared to traditional clay bricks.
5. Environmentally Friendly: While not directly related to durability, it’s worth noting that fly ash bricks are more environmentally friendly than red bricks, as they utilize fly ash, a byproduct from thermal power plants.
However, it’s important to note that the quality and durability of fly ash bricks can vary based on the manufacturing process and the quality of raw materials used.
