Fly ash bricks are a type of brick made from a mixture of fly ash, a kind of fine grey powder that is created when coal is burned, and a binding agent, such as cement or lime.
Think of it like making sandcastles at the beach. You mix water and sand together, and then shape it into a castle. Similarly, fly ash and binding agent are mixed together in a big drum, and then poured into a mold to make a brick.
These bricks are environmentally friendly because they use a waste product (fly ash) instead of traditional clay bricks which require digging up land and using a lot of energy to shape them. Plus, by using fly ash instead of dumping it in landfills, we can avoid creating pollution and ensure a cleaner environment.
Fly ash bricks are also very strong and durable, and can last for a long time when used in construction. In fact, they are even stronger than regular clay bricks, making them great for building houses, schools, and other buildings.
And that is how fly ash bricks are made and why they are good for the environment and construction!
