Modelling the behaviour of oil well cement paste: A challenge spanning from the early age to the hardened state

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We present a constitutive model for the cement paste, spanning from its earliest age to the hardened state, developed with the purpose of modelling the behavior of the cement sheath in oil wells. The model predictions are evaluated by simulating the results of mechanical loading experiments in a device specially designed for testing the thermo-mechanical behavior of cement paste from the early stages of hydration. The applications highlight the importance of the loading history and the role of the model mechanisms in the observed macroscopic behavior.
