Abstract

In this study, first of all, the atomistic structure of cement hydration products is estimated via molecular dynamics method and their elastic properties are extracted. Then, cement hydration simulation is done by HYMOSTRUC3D model and the obtained results from both molecular dynamics and HYMOSTRUC3D methods are used for simulation in macro-scales through analytic and lattice methods. Finally, elastic properties of cement paste are estimated with two mentioned methods and compared with each other and also with literature. The study, in fact, aims to investigate an appropriate multi-scale simulation model to examine cement paste elastic properties.
