“…The basic reason is that the steel substrate dominates the tensile and fatigue properties of ECRs. Even when considering corrosion, researchers prefer to investigate corrosion resistance based on individual electrochemical theories or by experiments on individual components, but mechanical tests are not involved [ 140 , 141 , 142 , 143 , 144 , 145 ].…”

Coated reinforcements are expected to improve the performance of reinforced concrete in aggressive environments, but different kinds of coated reinforcements can express a variety of properties, which can confuse researchers and engineers. This paper reviews the manufacture, corrosion mechanisms, behaviors, and applications of popular or promising coated reinforcements, incorporating galvanized reinforcements (GRs), epoxy coated reinforcements (ECRs), stainless cladding reinforcements (SCRs), and steel-fiber reinforced polymer composite bars (SFCBs). In terms of manufacture, GRs and ECRs should focus on minimizing the negative effect of manufacture on performance, while SCRs and SFCBs should reduce the cost and increase the production capacity. Behaviors of GRs and ECRs are primarily determined by the steel substrate, but the behaviors of SCRs and SFCBs are primarily affected by the coat and core, and their interaction. The corrosion mechanism of GRs and SCRs is about oxidation, while that of SFCBs is about hydrolysis. ECRs are usually corroded under film, which can be a cause of premature failure. Corrosion embrittles SCRs, as well as bare bars, but corrosion of SFCBs usually causes a reduction in maximum strength. The investigation of the corrosion behaviors of GRs and ECRs focuses on bond strength. GRs have controversial performance. ECRs have been proven to have drawbacks regarding bond strength. The use of anti-corrosion reinforcement is uneven in regions, which may correlate with the development of technology and the economy.

“…Steel and similar metals tend to react with their environment’s elements and turn into compounds . The most common corrosion types are known as uniform corrosion (homogeneous, evenly distributed), galvanic corrosion, pitting corrosion, crevice corrosion, selective corrosion, intergranular corrosion, and erosion-corrosion. − To eliminate the losses in load-carrying capacities, various studies have been carried out in the literature on the steel elements that have undergone corrosion and loss of section. − Also, the most critical zone in steel buildings is the connection zone; research on various connections has been done in the literature, and research is still being done on the behavior of connections after corrosion 39-4and fire. As a result, one of these connections is the T-section beam-column connection; − much research has been done in the literature, but there is very little research on the T-section beam-column connection after the fire and corrosion.…”

The most common type of connection in steel structures is the T-section connection. Steel structures can be damaged due to environmental effects such as earthquakes, fires, corrosion, etc., in real applications used in industry. Therefore, in this study, the corrosion and fire condition effects that occur in the T-section connection on the behavior of the connection zone were investigated. The study was carried out with 18 T-section connections with various corrosion (hydrochloric acid and sulfuric acid) in different layers at 5, 10, 15, and 20% corrosion levels, and fire (ISO834) conditions after corrosion have been evaluated and compared. T-section-bolted joints examined in the study were produced using IPE300 standard profiles. In the first part of the study, the behavior of the 18 T-section connections under an axial tensile load has been determined experimentally. The second part created a finite element model with the ABAQUS program for all models. It was seen that the finite element model analysis results converged with the results obtained as a result of the experimental study. As a result, compared to H2SO4 corrosion, HCl corrosion has little effect on the load–deformation characteristics of the connections. Also, if corrosion specimens are exposed to fire, then the connections will change from semirigid to hinged.

The various root causes of the failure occurred within the structure, the fortification on its failure, anatomy of the structural repair, the exclusive facts associated with innovative methods and protective treatment and lots of a lot of things are mentioned and presented during this project report. The target of building maintenance to form the building and their connected services are in the secure and guarded condition, to grant guarantee that the condition of building meets all legislative standards and requirement to perform the upkeep work indispensable to uphold the worth of physical assists of the building and additionally to accomplish the work essential to keep up the prevalence of the building maintenance. In a world today main problem is corrosion its losses economic and life. Corrosion can be prevented but not long time. Hence, we find out new treatment called as Sanjivani, and it is best for corrosion removal in current time comparatively other methods. Comparison analysis and test conducted result and equation and formula and whole procedure is given in our research paper. This is newly invented by us, still test going on it, it is future of maintenance repair and biggest assets war again corrosion. We have included various prevention measures and corrosion removal techniques used in industry and market currently and we have analyzed it by our point of view and given diagrammatic representation of methodology in form of flow chart and various apparatus used its benefits over existing methods advantages and old principle required for our test equation and derived our results and conclusion using standard norms.
