The effects of nano-silica on early-age hydration reactions of nano Portland cement
Abstract
The hydration reactions of nano Portland cement (NPC) with and without nano-silica (NS) additives were realized and tracked for the first time in a liquid cell transmission electron microscope (LC-TEM), coupled with isothermal calorimetry and quantitative X-ray diffraction (QXRD). We revealed the different hydration mechanisms in NPC and PC in the presence of NS. The results showed that NS shortened the dissolution and induction periods of the …
