After having studied phenomena linked to hydration and self-desiccation, one notes that capillary depression is the main origin of the autogenous shrinkage of hardening cement paste. Based on this mechanism, modelling at macroscopic scale is undertaken for a commonly used cement paste (CPA 55) with

We thank J. Baron and M. Buil for their reference to our work and for the interesting comparison they have made with their experimental results.
Fresh cement slurries typical of those used in the oil industry during drilling operations are assessed for the growth of structure in the first few hours after mixing by the use of shear modulus and ultrasonic pulse velocity measurements. It is shown that during the first two hours, the shear modul
