Abstract
A very slow creep test was performed on an Avery island salt sample. The testing device was set in a remote gallery of the Varang&*#233;ville Mine to take advantage of the very stable temperature there. This multi-step test was 30-month long. The applied load was 0.1, 0.2 and 0.3 MPa, successively. Steady-state strain rates are of the order of 10-12 s-1, significantly faster than what can be extrapolated from creep tests performed under larger load, Rates are an increasing function of the applied load.
