Finite element analysis and material modelling of concrete structures in the hardening phase

The Ph.D. project involves comprehensive creep tests for several types of concretes containing mineral additives, test results show that mineral admixtures can be beneficial in reducing cracking risk for young concrete. Viscoelastic properties under compression and tension are also investigated. Based on experimental data and well-documented material models which are verified by analysis of restraint stress in TSTM, the finite element program Diana is applied in cracking risk predictions for structures.
