High-Volume Fly Ash Concrete

The objective of the proposed study is to design, test, and evaluate high-volume fly ash concrete mixtures (HVFA). Traditional specifications limit the amount of fly ash to 40% or less cement replacement. This program attempts to increase the ash content to 75% while maintaining strength and durability characteristics. Various mixtures and chemical additives will be tested. The funding would allow calorimetry studies of potential admixtures and additives necessary to increase the percentage of fly ash (FA) in the various concrete mixes. The calorimetry would allow a more diverse and extensive set of variables to be studied, and would assist the researchers in developing mixes specific to each type of fly ash available. The funding would also allow testing for leachability of the HVFA concrete to existing FA concrete and non-FA concrete using TCLP, ASTM 3987, and the new LEAF methods, and to potentially evaluate the various products for radioactivity.
