Abstract Concrete, like many other materials (whether man-made, geological or biological), is a highly heterogeneous material with heterogeneities that manifest themselves at multiple scales. As new experimental techniques such as nanoindentation have provided unprecedented access to micro-mechanical properties of materials, it becomes possible to identify the mechanical effects of chemical reactions at the micro-scale, where the reactions occur, and trace these micro-chemo-mechanical effects through upscaling techniques to the macro-scale. The focus of this paper is to review recent developments of a microchemomechanics theory which ultimately shall make it possible to capture chemomechanical deterioration processes at the scale where physical chemistry meets mechanics. This is illustrated through application of the theory to early-age concrete and calcium leaching, and an outlook to biologically mediated deterioration processes in solid materials is given.
