Coal ash to concrete

In the article “Researchers turn waste from coal power plants into concrete” (NaturalBlaze, 2019), researchers from Drexel University have discovered a new method to turn coal ash, an abundant waste product, into an additive to increase the durability of concrete in buildings.

The additive is added to concrete, which is a composite mix. The water and cement within the mix are adhesives that bond other components together. A tedious process is needed to achieve maximum durability. By retaining water and supplying it to the surface, the mixture starts drying from the inside.

This method not only helps to ensure thorough drying but also reduces waste in the environment. This puts coal ash, which would otherwise be discarded, to use - making buildings more durable than before.
