Abstract

To fundamentally understanding the drying behavior of cementitious materials, this paper presents a microstructure-based approach to model the drying process in pores and the shrinkage of cement specimens. At high relative humidity (>84% RH), on the basis of Kelvin-Laplace equation and a microstructure model HYMOSTRUC3D, the drying process in capillary pores is simulated by several algorithms. Considering the drying deformation of calcium silicate hydrate (C-S-H) and assuming the capillary pressure in capillary pores as the main responsible stress for the drying deformation, the shrinkage of cement paste at different RH is calculated by three-dimensional lattice analyses.
