Modelling macroscopic shrinkage of hardened cement paste considering C-S-H densification

Autor: Rui Faria, Miguel Azenha, Hadi Mazaheripour, Guang Ye

Publikováno v: Advances in Cement Research. 33:257-284

Shrinkage of hardened cement paste is a direct result of its desorption isotherm. The relationship between the desorption isotherm and the relative humidity in a hydrating cement paste is mainly controlled by the pore size distribution (nanopores to

Microstructure-Based Prediction of the Elastic Behaviour of Hydrating Cement Pastes

Autor: Hadi Mazaheripour, Rui Faria, Guang Ye, Erik Schlangen, José Granja, Miguel Azenha

Publikováno v: Applied Sciences, Vol 8, Iss 3, p 442 (2018)

The development of the elastic properties of a hardening cement paste results from the microstructural evolution due to cement hydration. The elastic behaviour of cement paste can be predicted by a combination of the hydration model and micromechanic
