Abstract: Abstract The existing macroscale models of the calcium (alumino)silicate hydrate (C-(A-)S-H), the main binder of concrete, assume that the nanocrystallites maintain random orientation under any loading conditions. However, using synchrotron-radiation-based XRD, we report the development… read more here.

Abstract: Abstract The elastic constants and the structural of low silica calcium aluminosilicate glasses with a low content of silica (5–25 mol%) and [CaO]/[Al2O3] =2, are investigated using molecular dynamics simulations. In particular, their elastic constants are… read more here.

Abstract: Abstract In order to understand how surface charge accumulation and other reactivity-related phenomena are controlled by the surface structure, it is necessary to have a detailed appreciation of the bulk glass structures. Here, we report… read more here.
