Abstract

A model is proposed which allows for the difference between instantaneous and slow deformations during loading and unloading (of a mixture based on mineral binding substances). At different constant deformation rates the model reflects the dependence of the relaxation phenomena on the velocity and describes the thixotropy loop.
