Fly Ash vs Clay Bricks: Which is Better for Modern Construction?

May 22, 2025

Choosing the right type of brick is essential to ensuring the long-term performance and efficiency of your building. While traditional clay bricks have been used for centuries, modern fly ash bricks offer distinct advantages in today's construction landscape.

What Are Clay Bricks?

Clay bricks are made by molding natural clay and firing them at high temperatures. They are strong and time-tested but come with a high environmental cost — clay extraction damages farmland and depletes natural resources.

Fly Ash Bricks: The Sustainable Alternative

Fly ash bricks are produced using industrial waste, making them an eco-friendly and resource-saving alternative. They're lighter, have smoother surfaces, and provide better insulation compared to clay bricks.
