In this paper, a back-analysis scheme for the determination of the properties of jet-grouted structures using thermo-chemical couplings is presented. Hereby, the temperature increase in the center of the jet-grouted column is monitored and compared with the result of a thermo-chemical analysis of the hydration process in the column. As regards the latter, a multi-phase hydration model taking the chemical composition of the employed cement (or blended cement) into account is used.
