What Does the Changing Face of Electricity Production Mean for Concrete?

Recent environmental regulations that require emissions-control systems and the abundance of natural gas as an alternative fuel to coal have led to a decline in coal-fired power plants—a trend that is likely to continue. The U.S. Energy Information Administration (EIA) forecasts that 42 percent of existing coal-fired generation capacity will retire by 2050. As fly ash becomes less and less available, State departments of transportation and their contractors will need to seek alternatives. Many are already considering other options, such as natural pozzolans. This article describes some of the research being conducted to address this situation, as well as some of the materials that are being considered as alternatives to fly ash.
