Abstract: At the nanoscale (from amstrongs to nanometers), nature manifests itself in a discrete way, and its description usually requires an implicit atomistic assumption. It is therefore obvious that both molecular dynamics and ab-initio calculations have presented themselves as the most useful computational tools to describe such a scale. In this work, a general overview on the description of cementitious materials by means of ab-initio calculations will be provided. Especially, it will aim to stress the tremendous capability of these techniques to explain and predict a wide range of parameters and processes which are inaccessible otherwise. In particular, some interesting examples will be discussed, such as the inherent capacity of the ab-initio calculations to describe the condensation reactions that take place during the hydration process and provide crucial information with regards to the stability of the possible species.
