Abstract:
For at least the past decade, almost half of the concrete mixtures produced in the United States have included fly ash (FA). However, the production of FA has diminished as coal-fired power plants are being retired and replaced by wind turbines, solar panels, and natural gas-powered plants. So, either new sources of FA must be developed, or industry will have to find other supplementary cementitious materials to fill the void.
