Abstract: 
This paper presents the numerically simulated pore structure of cement paste with the cement hydration model HYMOSTRUC. By using a serial section analysis, in combination with an "overlap algorithm", several geometrical parameters, such as internal surface area, volume of capillary pores and characteristic pore size distribution are derived. Experimental method, such as backscatter environment scanning electronic microscopy (ESEM) and mercury intrusion porosimetry (MIP) are used to determine the pore structure of cement paste. Measurements were performed for the cement paste with different water to cement ratio at an age of 1, 3, 7, 14 and 28 days. The quantitative comparison between simulated pore structure and experiments are presented and discussed.
