This study provides the first detailed insight into composition and properties of structural mortars used in a 4th-century AD bath complex Aquileia, emblematic center Roman culture Northern Italy. Eighteen mortars, taken from different structures site, three stone samples vaulting opus caementicium have been analyzed adopting multianalytical approach integrating optical microscopy, X-ray powder...

Integrated spectroscopic analyses and synchrotron X-ray microdiffraction investigations provide insights into the long-term reactivity of volcanic aggregate components calcium-aluminum-silicate-hydrate (C-A-S-H) binder in mortar samples from robust concrete sepulchral corridor Tomb Caecilia Metella, 1st C BCE, Rome. The results innovative micrometer-scale analytical maps indicate that Pozzolane...

In this paper, the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale, because of its analogous chemical composition to C-S-H. Aluminum incorporation in C-S-H and...
