Characterisation of cement‐based materials by 2D and 3D analytical SEM

The demands on modern building materials are constantly increasing. Innovative solutions produce a multitude of binders and concretes that often have a very complex, multiscale heterogeneous composition. Multi-scale imaging of structural characteristics is still a challenge but will provide basic understanding…

PARAMETER IDENTIFICATION APPLYING IN COMPLEX THERMO-HYDRO-MECHANICAL PROBLEMS LIKE THE DESIGN OF BUFFER ELEMENTS

This study contributes to the identification of coupled THM constitutive model parameters via back analysis against information-rich experiments. A sampling based back analysis approach is proposed comprising both the model parameter identification and the assessment of the reliability of identified…

Numerical simulation and inverse analysis of thermo-hydro-mechanical behavoir of sand-bentonite mixture

Sand-bentonite mixtures are well recognized as buffer and sealing material in nuclear waste repository constructions. The behaviour of compacted sand-bentonite mixture needs to be well understood in order to guarantee the safety and the efficiency of the barrier construction. This paper presents numerical…
