This study investigates the effects of chloride environment exposure on the flexural performance of strengthened RC beams with self-anchored prestressed CFRP plates. In total, seven RC beams, four of which were strengthened by a self-anchored prestressed CFRP plate, were fabricated and tested under ...
Pristine silver nanopartides (AgNPs) are not chemically stable in the environment and react strongly with inorganic ligands such as sulfide and chloride once the silver is oxidized. Understanding the environmental transformations of AgNPs in the presence of specific inorganic ligands is crucial to determ...
This paper presents a comprehensive parametric study to determine the effect of different factors on the service life of reinforced concrete structures in chloride-laden environment. A model for corrosion initiation is selected and solved numerically by Finite Element Method for one-dimensional diffusion ...
On the other hand, the effects of chloride ions on the corrosion kinetics are also controversial. Allamet al.16, focusing on atmospheric situations, revealed that chloride ion only functioned during the corrosion initiation and failed to penetrate through the thick rust layer at later stages. This...

These RTP effects could be observed easily by the naked eye after the UV lamp was switched off (Fig. 3c-k). We thus suggest that MgCl2 treatment pro- vides a general means of preparing afterglow materials from wood. Additionally, the long-lived RTP lifetime of C-wood using different wood...
