A 29Si MAS NMR study of modified C–S–H nanostructures

The sustainability of cement-based materials is a core technical issue of national importance. The serviceability of the concrete infrastructure, especially bridges, has recently received considerable media attention. Concurrently, the nanoscience of cements has emerged as a new discipline with the potential to positively manipulate the nanostructure of calcium silicate hydrate (C–S–H) in order to achieve sustainability objectives. …
