Chemomechanical coupling in concrete are the multiple cross-effects between chemical reactions and deformation which can lead to cracking. These chemical reactions take place, typically at a scale much below the macrolevel of engineering material description. The paper shows how this problem can be treated at the macroscale of engineering material modeling within the framework of plasticity of chemically reactive porous media. The paper gives an overview on recent developments of thermo-chemo-mechanical couplings in early-age concrete related to the hydration reaction. These thermo-chemo-mechanical couplings are explored from the macroscale of engineering material modeling to the level of structural design.
