Abstract
Rheological properties of salt rocks are generally studied within long time (days, months). Salt rock short-term (within minutes or tens of minutes) rheological behavior analysis is of interest being concerned with construction of models of salt rocks mechanical behavior under active loads and within short time; interpretation of standard test data (ultimate compressive strength, ultimate strain, modulus of deformation, etc.), obtained at a constant rate of loading within specified time. Results of the rock salt specimen tests conducted in the Zwick/Roell-Z250 universal testing machine are presented laying special emphasis on the specimen geometry effect on the short-term relaxation and creep rate.
