Research Theme
In this study, the diffusivity of concrete damaged by loading and/or freeze-thaw cycling is investigated numerically based on Rigid Body Spring Model (RBSM) and Truss Model. Subsequently, the durability evaluation of a damaged concrete structure exposed to salt environment can be carried out.
Research Summary
Background
For concrete structures exposed to salt environment, the microstructure and cracks play a crucial role in the ingress of chloride ions into concrete. In this study, concrete is simulated on the meso scale as a three-phase composite, i.e., aggregate particles, mortar and the interfacial transition zone (ITZ). Because of the advantages in simulating cracks behavior in concrete, RBSM is employed to clarify the damage (cracks) of concrete. And then, the truss model is used to evaluate the chloride permeability of the damaged concrete.
