A mathematical model of the behaviour of concrete backfill in an underground waste repository

Abstract

This report concerns the mathematical modelling by the finite element method of the behaviour of concrete, one of the candidate materials for use in the backfilling and sealing of underground repositories for radioactive waste. The present study is predominantly concerned with the development of a mathematical model for use within the ADINA finite element code to predict the time-dependent performance of concrete as a backfilling and sealing material. The finite element material model developed accounts for the ageing of concrete, multi-axial creep and creep recovery, the effect of external environmental humidity and changing internal temperatures. The model compares favourably with available published experimental data for maturing concrete but requires considerable further validation against a wider range of experimental results. (author).
