Extension of the Hymostruc3D model for simulation of hydration and microstructure development of blended cements

The HYMOSTRUC3D model has been used successfully to predict hydration and microstructure development of pure Portland cement paste. In recent years, a number of numerical models were proposed for optimizing the use of supplementary cementitious materials. Also HYMOSTRUC3D was extended for simulating the hydration and microstructure development of Portland cement blended with blast furnace slag or/and fly ash (Gao, 2018). This paper summarises the main features of this extended model, called HYMOSTRUC3D-E, and demonstrates the simulation of the hydration process and pore solution chemistry of slag cements.
