Abstract: This paper reviews the present stage of cement hydration and microstructure simulation program HYMOSTRUC, which was developed at Delft University of Technology, the Netherlands, for simulating the evolution of concrete properties. In the HYMOSTRUC program, cement hydration is simulated as a function of the particle size distribution and the chemical composition of the cement, of the w/c ratio and of the reaction temperature. The program starts from the cement particles size distribution in a 3D body, the cement particles were considered as individual spheres. Based on an "interaction expansion mechanism", the cement grains gradually grow in outward direction. With progress of the reaction process the growing particles become more and more connected. In this way, a virtual microstructure is formed. In this paper, the principle of HYMOSTRUC model are described, the application of this program on the early age properties, the mechanical properties and durability of cementitious materials are presented.
