Abstract
The chemical environment of barium in Portland cement which is doped with barium nitrate was investigated using x‐ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared spectroscopy (FTIR). The barium doped cement showed tremendous increases in carbonate content over the undoped cement. An XPS sulfate signal was observed in the cement doped with 20% w/w Ba(NO3)2 but not in the 0 and 10% w/w doped cement. FTIR and XPS results lead us to believe that the barium exists as both BaSO4 and BaCO3 in the cement matrix.This publication has 7 references indexed in Scilit:
