Therefore, in this paper, we derive an analytical model to efficiently predict the elastic properties (e.g., Young's modulus) of hydrating cement paste. Notably, the proposed model provides the prediction of hydration, percolation, and homogenization of the cement paste, enabling the study of the early age elasticity evolution in cement paste.
