Simulation of hydration and microstructure development of blended cements

For optimization of the use of Supplementary Cementitious Materials (SCMs), i.e. blast furnace slag (BFS) and fly ash (FA), in cementitious system a numerical model for simulating the hydration and microstructure development of blended cements can be used. Several models have been proposed in recent years to simulate the hydration and microstructure development of blended cements. However, most of these models need further development. For example, the nucleation and growth of calcium hydroxide (CH) particles were often not simulated explicitly in these models.
