  • Method for determining a plasticity parameter of a hydrating cement paste
    Patent number: 11287413
    Abstract: A method for determining a plasticity parameter of a hydrating, cement paste by mixing the components to obtain a cement slurry, pouring the cement slurry in a scaled oedometric cell, and performing an oedometric measurement operation within a predefined early-age time interval by applying a predefined axial stress path to the cement slurry over a predefined measurement duration and measuring an axial strain. A plasticity parameter of the hydrating cement paste is determined b a calibration processing operation comprising providing an initial value of a plasticity parameter of an elastoplastic model of hydrating cement paste, determining simulated axial strain values by solving the elastoplastic model of hydrating cement and comparing the simulated axial strain values with the axial strain measurements of the cement slurry.
