Louisiana Tech researchers are developing a geopolymer concrete, also known as GPC, that uses fly ash produced by coal-fired power plants. The researchers note that using the fly ash in concrete will prevent the byproduct from going to landfills. They also hope that GPC eventually replaces Portland cement, the production of which has been linked to global warming. "It is important research for the U.S. because it's environmentally friendly," noted Ivan Diaz, a doctoral candidate.
