Abstract:
Many structures around the world suffer from alkali-silica reactions. A new mod- elling is presented for kinetics and expansion prediction of ASR degraded concrete. It is based on an homogenisation method and it allows to take into account the aggregate size grading effect on both kinetics and expansion. Constitutive equations, based on diffusion equations, are developed in this paper. Experimental data are used for fitting themodelling. Experimental and numerical results are presented.
