“…Therefore, concrete must be water cured within about 15 minutes after final finishing to avoid plastic shrinkage cracks. Curing should be continued for seven days so that the concrete attains a strength equal to 70% of its design strength [26]. To keep concrete wet continuously during the curing period; pigments, heavy-duty curing compounds, plastic sheets, waterproof papers and other wet materials may be used.…”

Corrosion is the most common structural defect in today's construction industry and therefore requires the most precautionary measures. As a result of corrosion, the repair of the structure causes high costs or is not possible at all. Corrosion inhibitors are the fastest and easiest method to take on corrosion, but many inhibitors used today contain components harmful to the environment and toxic. Today, there is hardly any concrete produced without using any chemical and mineral additives. Researchers are trying to produce less harmful concrete chemicals. In this study, calcium nitrite, which is the most widely used corrosion inhibitor in the market, and ecological boron inhibitor were compared with experimental methods. In addition, the interaction of chemical additives used most in concrete production with these inhibitors was investigated. As a result of experimental studies, it was concluded that the ecological boron inhibitor did not damage the structure of the reinforcement in the concrete and could be used instead of the calcium nitrite inhibitor produced in the market. The electrical resistance, rapid chloride permeability and half-cell potential experiments show that samples containing boron inhibitors gave the best results compared to other samples.

“…The choice of the inhibitors was based on preliminary studies performed on the bare steel specimens in synthetic solution prepared by bubbling carbon dioxide in saturated solution of calcium hydroxide. The details of the preliminary tests are reported in Kaur et al 2016. From the preliminary studies, it was established that amino alcohol based commercial inhibitor (C.I.…”

In this paper, electrochemical impedance spectroscopy was used as non destructive technique (NDT) for studying the carbonation behavior of the concrete sample treated with migratory type of organic corrosion inhibitors. Concrete carbonation was achieved in carbonation chamber by maintaining 5% CO 2 by volume, 60-70% relative humidity and 30 ± 2°C temperature for 90 days. The experimental results show that with progressive carbonation, porosity of the concrete reduces and results in denser microstructure. The concrete surface treated with corrosion inhibitor C.I. 1 (amine -ether based) and C.I. 2 (2-aminobenzoic acid) shows the behaviour different form the control sample at the end of exposure conditions. Impedance results indicate that carbonation depth can be predicted by analyzing the high frequency arc of Nyquist plot. Also, both of the tested inhibitors were able to form a passive layer around the rebar surface and their efficiencies improved with time.

“…It is not possible to eliminate altogether corrosion occurring in concrete but several corrosion control strategies which focus on either altering the corrosion mechanism or delaying the same have been reported. Researchers have reported to delay corrosion of reinforcing steel by reducing permeability of the concrete by introducing admixtures in concrete mix like fly ash, polymer fibers or healing microcapsules [9][10][11][12][13][14], or by applying coats or surface treatments on the concrete surface to make it impermeable [15][16][17][18][19], or by using corrosion inhibitors which prevent the entry of aggressive ions into the concrete [20][21][22][23]. Use of protective/sacrificial coatings on the reinforcing steel like galvanization, epoxy-based coatings, and zinc based cathodic protection etc.…”
