water content

This research explores the combined effects of chloride ions, carbonation, and relative humidity on rebar corrosion in mortar. It reveals how these factors influence the volumetric water content and resistivity of mortar, resulting in complex corrosion behavior. The study emphasizes the importance of considering these interactions for accurate corrosion prediction and enhanced durability of reinforced concrete structures.

This study investigates the impact of cracks on water flow in concrete. It examines both artificial and natural cracks of varying widths (0.3 mm and 1.0 mm) under wetting and drying conditions. The Time Domain Reflectometry technique is used to monitor water content evolution around the cracks, revealing that all types of cracks behave similarly to open surfaces exposed to environmental elements.
