Abstract
As part of an ongoing development, this paper presents a brief description of a new Chemo-Mechanical (C-M) model for the expansions due to Alkali-Silica Reaction (ASR) in concrete. This model has been formulated at the meso-scale level (major aggregate fraction and cementitious matrix of cement paste or mortar). The chemical and the mechanical problems are solved by means of two different Finite Element (FE) codes coupled via a staggered implementation. Both codes use the same FE mesh, which can...
