  abstract: The behavior of the steel-grout interface is dependent upon the thermal and mechanical characteristics of the two component materials. To understand the behavior at the interface, the problem was studied in two parts. The first part consisted of analyzing numerically the response of the interface when subjected to the time-temperature history of the grout hydration process. During this process, there are large temperature changes in a relatively short period of time, as well as dramatic changes in the properties of the grout. Indeed, the grout changes from a visco-plastic fluid, to a fairly compressible and porous skeletal structure of partially hydrated compounds, to a hard brittle solid. The separation of the interfaces (debonding) is a possibility during this phase. The analysis is done using a realistic time-temperature history based on scale models, material properties determined in laboratory tests, and assuming actual field conditions. Debonding of the interface can lead to significant loss of load-transfer capacity of the structure. The second part consisted of studying experimentally the strength of the interface during the post-hydration period. At this stage, the grout has gained most of its strength. Analytical models have been developed to predict the interface stresses that can occur in a drilled and grouted pile under actual field conditions. A design equation is proposed for the interface bond strength.
