Competence to combat corrosion of steel‐reinforced concrete (SRC) infrastructures for long periods has become a fascinating topic for corrosion scientists. The longevity of such infrastructures is limited mainly by the corrosion process. Hence, urgent demands for developing effective and practical methods are necessary to minimize the corrosion of such concrete structures. The anti‐corrosive components can be designed from the green plants' parts to mitigate the SRC corrosion in recent years. The ongoing research aims to substantiate the success of the leaf extract of Psidium guajava (LEPG) and its 50% blend (BnD) with the leaf extract of Mangifera indica (LEMI) for assessing the steel corrosion condition in a concrete slab. For this purpose, a fast corrosion potential monitoring (CPM) method is applied per the ASTM procedure. Outcomes of the work summarized that the additions of 500–4000 ppm LEPG and its 50% BnD blend have significant corrosion‐inhibiting action. The corrosion potential (ϕcorr) shifts toward a less corrosion‐risk area of the steel bar for 6 months at ambient conditions.

Synthetic water repellent (WRep) generally blocks the ingress of corrosive factors like moisture and various gases to the reinforced steel (RS) surface through the concrete pores. Mixing such WReps in the concrete mix did not affect the anti-corrosive response to the RS infrastructures. Considering such consequences, the present work explored the uses of two synthetic water repellents (e.g., WRep-A & WRep-B) and plant-derived green inhibitors to control the corrosion stability level of the RS in the concrete matrix. The broader question of the work is to know whether the water-repellent affects the anti-degradation response to the steel in concrete at the same patterns as commonly practiced in the concrete matrix or differently when the cast reinforced concretes exposed to water-repellent suspension for a certain curing time. The concrete slab exposed for one week to the suspension mixture of 1000 ppm WRep-B+Mangifera indica (WRep-B+MILE) and 1000 ppm WRep-B+Psidium guajava (WRep-B+PGLE) extracts exhibited maximum anti-corrosive response, which is justified by corrosion potential shifting to a more positive potential zone where the reinforced steel corrosion damage state rated as <10% probability and anticipated more effective corrosion inhibiting activities compared to other concentrations used in this work.

Concrete infrastructures with embedded mild steel (EMS) have been implemented in various construction sectors to enhance their strength and durability. However, deleterious corrosion of the EMS in CA is a burdensome problem worldwide. Therefore, timely application of appropriate corrosion control techniques can mitigate the consequential effects of premature corrosion of such EMS in CA. Green plant-based leaf extracts have been recently utilized as anti-corrosive agents to prevent premature EMS corrosion. The present work focused on exploring the inhibitory impacts of leaf extracts of floss flower or Ageratum houstonianum (AgHE) and yam or Dioscorea alata (DiAE) each for controlling the rusting of the EMS in concrete beam (CB). The DiAE and AgHE comprise secondary metabolites like phenols, alkaloids, saponins, steroids, tannins, and flavonoids, confirmed from screening, GC-MS, and FTIR analysis. The EMS in CB with 1000-4000 ppm DiAE or AgHE showed a better corrosion inhibiting effect, compared with a concentration of 500 ppm from the observation of electrochemical corrosion potential (ECoP) value, measured using half-cell potential (HCP) method according to the ASTM C876-91 standard. The recent outcomes could be a part of an innovative solution to extend the lifespan of EMS in CB.
