Dedolomitization and Alkali Reactions in Ohio-Sourced Dolostone Aggregates

The data collected from this project could provide petrographical and chemical evidence of dedolomitization of Ohio's dolostone aggregate sources over regular intervals of time using different methods, and will contribute to the Ohio Department of Transportation's (ODOT's) new concrete freeze thaw test parameters. The goal of this project is to employ state-of-the-art scientific/analytical methods for sample characterization and analysis including using Polarized Light Microscopy (PLM), Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray microanalysis (SEM?EDS), and X-ray Powder Diffraction (XRD) to identify the presence of dedolomitization in Ohio-sourced dolostone aggregates and concretes produced using these aggregates. This project will be overseen by Dr. John R. Farver of Bowling Green State University.
