Summary:This paper describes unconfined creep tests and cyclic tests performed to characterise creep behaviour and fatigue behaviour of Fontainebleau sand grouted with three types of grout, a silicate grout, a micro-fine cement-based grout and a mineral-based grout. Results are compared in terms of strain rate, creep slope or fatigue slope, and creep limit strength or fatigue limit strength. These tests make it possible to show some analogies between creep behaviour and fatigue behaviour on the one hand from a qualitative point of view since creep curves and fatigue curves have the same shape with the presence in both cases of primary and tertiary behaviours and on the other hand from a quantitative point of view under certain loading conditions.
