Influence of cracking on chloride diffusivity and moisture influential depth in concrete subjected to simulated environmental conditions

Theoretical and Experimental Investigation of Loading Effects on Chloride Diffusion in Saturated Concrete

“…In order to accurately predict the service life of RC structures suffering from chloride attack, it is necessary to quantify the chloride penetration process in concrete. To fulfill this goal, extensive research has been conducted by previous researchers to investigate the concrete chloride diffusivity, which is commonly regarded as one of most important parameters affecting the structural durability (Bentz and Thomas 2001;Kato et al 2005;Wang and Ueda 2011;Ye et al 2013Ye et al , 2015. Basically, chloride penetration in saturated concrete is facilitated by the network of interconnected pores in concrete, as far as the chloride concentration gradient exists between the external exposed surface and the interior pore solution (Martın-Pérez et al 2001).…”

A phase-field approach to fracture coupled with diffusion

“…The brazilian test [30], the wedge splitting test [35], the three-point bending test [36] and the expansive core test [27] are four widely used experimental set-ups for measuring mechanical properties and generating cracks in cementitious specimens. [29,45,43,46] Cracked specimens are then employed to measure their diffusion properties, with either conventional methods [27,37] or accelerated methods [34]. Conventional methods are e.g.…”

An Experimental Study on Relationship among Water Sorptivity, Pore Characteristics, and Salt Concentration in Concrete

“…The initiation of corrosion originates from a high chloride concentration in pore solution which depassivates the protecting film around rebars [3]. In order to accurately predict the time from construction to corrosion initiation, it is essentially important to characterize the chloride ingress process in concrete cover [4][5][6]. However, depending on the exposure condition, the members of marine structures are typically exposed to four different types of chloride-bearing environments: submerged zone, tidal zone, splash zone, and atmospheric zone.…”
