Sažetak
Cement is one of the most used materials on Earth and it is modelled by calcium silicate hydrate. Using density functional theory methods we calculate infrared spectra of several Ca-Si-O-H nanoparticles. A specific calcium silicate hydrate feature at 14 microns together with typical silicate bands at 10 and 18 microns could be used for detection of cement in Space. We found 14 microns band in spectral features of several oxygen-rich circumstellar dust shells observed by ISO and classified as remaining.
