This talk will present characterization, processing, and high-volume use of industrial waste products in producing high-performance concrete for infrastructure applications. Specifically, we will focus on the fluidized bed combustion (FBC) technology that is widely used in Pennsylvania for environmental cleanup of waste coal (gob) piles and producing electricity. The byproduct FBC ash contains dehydroxilated clays which can beneficially react with Ca- and Al-bearing phases in concrete. Opportunities and challenges will be presented.
