Concrete made from coal ashes proves to be just as resistant as concrete from quarry aggregates
A University of Cordoba research team in partnership with the University of Navarra successfully uses waste from thermoelectric plants instead of natural resources to make concrete for structural use and demonstrates that it has the same characteristics for construction.
Overexploitation of quarries in order to obtain sand and gravel needed to produce concrete is currently one of the most challenging environmental issues. Rocks are not inexhaustible, though they may seem. So, for years the scientific community has been searching for a way to manufacture concrete without depleting the Earth’s crust. This is done by approaching the issue from different perspectives. This is the case of two University of Cordoba research teams that worked together in order to obtain a material that is just as sturdy and durable, but more sustainable. This was done by chemists and engineers working closely together.
