Web17 dec. 2024 · Abstract. In order to investigate the influence of calcium sulfate whisker (CSW) on the high temperature performance of asphalt binder, two types of CSW, calcium sulfate hemihydrates whisker (HCSW) and calcium sulfate anhydrous whisker (ACSW), were used. WebThese two hemihydrates also have similar and much higher values of Δ S° dis than the other hydrates, and their IR spectra suggest that they may contain Type I planar (H 2 O·I -) 2 cluster ions. The IR spectra of all of the other iodide hydrates studied show Type II extended linear HOH ⋯ I -hydrogen bonding.
