Abstract: Calcium leaching and chloride penetration are modeled with regard to concrete chemical degradation and corrosion risk of steel reinforcement in RC structures. The presence of propagation fronts that move at finite velocity ...

Abstract: The risk of early-age concrete cracking depends on the capacity of hardening concrete to support the thermal stresses caused by the exothermic nature of the hydration process. This has been recognized for “massive” concrete ...

Abstract: This paper explores the theory of reactive porous media in the modeling of thermochemomechanical couplings of concrete at early ages. The formulation is based upon thermodynamics of open porous media composed of a skeleton ...

Abstract: This paper is concerned with modeling, identification, and experimental determination of thermo-chemo-mechanical couplings in early age concrete for the prediction of deformation and cracking on account of strength growth ...

Abstract: Modeling of the drying of porous materials is often approached by assuming that the gas pressure of the vapor-air mixture remains constantly equal to the outer atmospheric pressure. Use of both experimental and theoretical ...

Abstract: The maintenance of a considerable number of concrete structures the durability and serviceability of which are endangered by the alkali–silica reaction (ASR) requires a quantitative structural evaluation and prediction, ...

Abstract: This paper and its companion paper present the main results of an assessment of the fire in the Channel Tunnel (the “Chunnel”), which destroyed a part of the concrete tunnel rings by thermal spalling. The study seeks (1) ...

Abstract: The critical nature of the alkali-silica reaction (ASR) on premature concrete deterioration requires the quantitative assessment, in time and space, of the chemomechanical impact of ASR expansion on the dimensional stability ...

Abstract: The main purpose of the present study is to investigate the role of the material parameters such as permeability, thermal diffusivity, and pore size distribution on the mechanical behavior of cementitious structures submitted ...
