Neutralizing the Adsorptive Effects of Carbon in Fly Ash for Use in Concrete

Fly ash has been used as a supplementary cementitious material in concrete for decades. However, not all fly ash is beneficially used because of adsorptive properties of its carbon content. This research will use industry techniques such as the foam index and foam drainage test to analyze admixture dosages. For this, it is necessary to evaluate each procedure published and establish the procedure, or combination of procedures, that has the optimal combination of low subjectivity, high reproducibility, and simplicity. Once established, these tests will be used to assess inhibitors. The goal is to find an inhibitor to mitigate the adsorptive properties of fly ash. Fly ash can then be a more reliable portland cement replacement in concrete.
