Liquid Cell Transmission Electron Microscopy Reveals C-S-H Growth Mechanism During Portland Cement Hydration
Abstract
We report the first application of in-situ liquid cell transmission electron microscopy (LC-TEM) to research hydration reactions of nano OPC, providing nanoscale insight into early reaction mechanisms. We demonstrate that the formation and growth of C-S-H precipitates starts through lateral growth of planar silicate sheets, but soon continues in all directions resulting in a 3D microstructure. Furthermore, nanocrystalline C-S-H structures with …
