Evaluation of Performance of Coal Ash in Florida Structural Concrete.

This research will review the existing literature on the procedures needed to produce concrete-quality pozzolanic materials from coal ash, based on whether the precursor materials were from landfilled, ponded, or as-collected coal ash sources. This will include the types of coal ash present and their chemical and mineralogical compositions. Any components of coal ash that could negatively affect the reactivity or long-term durability of concrete shall be identified along with procedures to remove them or mitigate their effects. Any components of coal ash that are leachable from concrete incorporating that ash, and that are known to be hazardous to health or the environment, shall be identified along with identified procedures or methods to remove or mitigate their effects.
