Abstract
Many studies have been done by some kinds of analysis to estimate mechanical properties of concrete : i.e. compressive strength and durability of concrete. But, the quantitative evolution about these properties is not complete, due to insufficient data on the microstructure of hardened cement. There are few studies about the microstructural development during cement hydration. Then, in order to clarify quantitatively mechanical properties of concrete, it is need to make a model of microstructural development during cement hydration, and to combine the field of cement chemistry and that of concrete technology.
