Abstract:In order to investigate the feasibility of rapid identification of chemical compounds or detection of certain additives or contaminants in commonly used construction materials with portable X-ray Fluorescence (XRF), stainless steel, anchor bolt, steel nut, steel washer, portland cement (type I, II, and III), class F fly ash, and aggregates were tested with the Olympus Vanta C series handheld XRF in this study. The same materials were also tested either with a spark spectrometer (for metal samples) or a benchtop XRF device (for non-metal samples) in DOTD materials laboratory. Through a comparison between the results from portable XRF and DOTD materials lab for metal samples, it shows the Olympus Vanta C series handheld XRF was able to detect manganese, nickel, chromium, and molybdenum, but it was not able to detect phosphorus, sulfur, and silicon that have a content value less than 1% in the metal samples. There is a linear relationship between the portable XRF testing results and DOTD materials laboratory testing results for the testing results of element copper, and manganese.
