Fly ash generated by coal power generation can be repurposed into geopolymer concrete. However, a critical durability problem has been low resistance to alkali attack. Researchers at the University of Johannesburg have found that high temperature heat-treatment at 200 degrees Celsius can halve this harmful mechanism in fly ash geopolymer concretes.
