Title: Understanding cementitious system at the atomic level

 

Cement hydration is a very complex process involving multiphase reactions through dissolution-precipitation pathways. These reaction pathways are inherently characterized by molecular mechanisms at the solid-liquid interfaces. With the immediate need to make cementitious systems carbon neutral, there is a requirement to generate knowledge about these materials and mechanisms at the atomic level. However, such level of information is often not easily accessible with experiments. Thanks to recent advances in computational methods and resources, atomistic simulation techniques have become increasingly accurate and are now extensively applied to investigate such mechanisms as well as some of the atomic level features of cementitious materials. In this talk, application of atomistic simulation methods such as density functional theory calculations and molecular dynamics simulations (both classical and ab-initio ) in cementitious systems will be discussed. With the help of a few examples, the relevance of such calculations as to how it can actually generate the essential knowledge towards better understanding of cement hydration reactions and related mechanisms will also be discussed.
