“…The construction industry, which includes the development of high-rise buildings, bridges, and highways, has been a major contributor to the economic growth of the country, owing to rapid urbanization. Concrete, being a reliable and durable material, is extensively used across the globe [1][2][3][4]. Despite its ability to withstand numerous deterioration processes, external factors can impact its overall health.…”

The prevalence of catastrophic structural member failure caused by steel corrosion in civil infrastructure underscores the importance of reducing reinforcement corrosion to enhance overall infrastructure costs, reliability, and sustainable development. This study examines the use of corrosion inhibitors to improve the durability and strength of concrete structures, with a focus on their long-term effectiveness in resisting corrosion in reinforced concrete structures. Multiple approaches such as inhibitors, repairing processes, and coatings have been explored to prevent concrete corrosion damage, with an emphasis on concrete corrosion performance in coastal and corrosive situations. This study investigates the effect of six different corrosion inhibitors (zinc oxide, magnesium oxide, urea, sodium nitrate, sodium molybdate, and diethyl ether) on the compressive strength, durability, and microstructural properties of concrete samples. The compressive strength is assessed using both destructive (28 days cube compressive strength) and non-destructive (Ultrasonic Pulse Velocity) test methods, while concrete durability is evaluated using the rapid chloride permeability test . SEM imaging is also conducted to analyze the microstructure of each mix. The findings of this study highlight the importance of inhibitors in enhancing the durability of reinforced concrete structures.

“…However, the behaviour of concrete is complex and depends on several factors such as the type of aggregates used, the water-cement ratio, curing conditions, and other environmental factors. The strength, durability, and performance of concrete are crucial parameters that need to be considered during the design and construction phase [1][2][3] . The microstructure of concrete, which is primarily determined by the hydration of cement paste, plays a significant role in determining its properties.…”

The piezoelectric patches paired with impedance-based signal diagnosis is one of the critical Structural Health Monitoring (SHM) techniques used for hydration monitoring concrete hydration. This investigation discusses the three different configuration PZT patches, instrumented on concrete cubes for assessing the hydration rate for concrete: (a) embedded in the concrete around the rebar, (b) affixed at the end of an aluminium foil embedded inside concrete. The hydration process was monitored considering statistical indices; root mean square deviation data (RMSD) were derived from sensor readings till 28 days of curing. Long-term (up to 28 days) hydration of concrete was assessed using the PZT sensors in these two configurations. Further, this study attempts to optimize the piezo-induced signal indices based on both sensor configuration. The magnitude of RMSD corresponding to the various frequency ranges obtained from PZT, and frequency based coupled parameters are derived to understand the hydration mechanism of the concrete.
