This thesis involves the investigation of the effects of Calcium Magnesium Acetate (CMA) deicers on Portland cement mortar bars. In addition to mass-loss, length change, pulse velocity and soak solution pH, the thesis also contains a rigorous chemical analysis of the mortar completed at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. The research completed at NIST was done using a technique known as X-ray Mapping. The X-ray techniques were employed to determine the exact nature of the damage caused by CMA. The thesis is a combination of two papers, on the physical effects of CMA and one on the chemical effects both of which contain numerous X-ray maps and examples for using X-ray microanalysis on concrete.
