Cement paste is the important component of other engineering heterogeneous materials, such as various kinds of concrete. Using the micromechanic approach, intrinsic elastic properties of individual components of cement paste are upscaled to the scale of tens of micrometers. Cement hydration model has been developed for a prediction of microstructures of hydrating cement paste and in combination with micromechanics provides sufficient tool for prediction of elastic properties. Both models are discussed as well as the computational requirements of homogenization. Validation on the pastes with water-to-cement ratii 0.2 - 0.5 shows good correlation with experiments.
