SIMULATION OF POZZOLAN BLENDED CEMENT HYDRATION

Pozzolan blended cement hydration reactions, the most promising route towards the sustainability of cementitious materials, have been simulated by Hymostruc, a numerical model for cement hydration and microstructure development. The 3D model calculates the progress of the hydration process as a function of the particle size distribution, water cement ratio, morphological development and chemistry. The paper presents a comparison of numerical results with systematic literature experimental data and demonstrates the potential to use particle-based numerical simulation models (growing spheres) to simulate hydration reactions in blended cement systems.
