    The Effect of Composition on the Alkali-Silica Mitigation Potential of Fly Ash-Ground Glass Blends in Concrete
    (2019-08) Doolittle, Nathan
    This research investigates the use of ternary blends of Portland cement, ground glass and four different fly ashes as a mitigation method for alkali-silica reaction (ASR) in concrete. ASR is the reaction between select reactive aggregates and alkalis in the pore solution of concrete added by the hydration of portland cement. The inclusion of fly ash and waste glass has potential to reduce the deleterious expansive effect of ASR. Testing conducted involves measurement of length change, compressive strength and the fresh mix properties.
