“…While carbonation implies a gas that needs the pore network partially empty (Pacheco, 2015). Many strategies were used to decreases the risk of concrete corrosion (Paul and Van Zijl, 2017;Zhao et al, 2017) such as using additives to the concrete mix (Goyal et al, 2018;Bamforth, 2004), coating the steel rebar and others (Bamforth, 2004;Broomfield, 2006;Berrocal et al, 2016;Osial and Wilinski, 2016).…”

It well known the advantages of using SiO 2 nanoparticles as additive for improving the mechanical properties of concrete structure and reducing the liberation of CO 2 gas to the atmosphere. This research investigate the effect of adding SiO 2 nanoparticles (12 nm; 1, 3 and 5% by weight) to artificial concrete solution (2gCa (OH) 2 , 0.0225 g KOH and 0.008 g NaOH in one litter of distilled water) on the corrosion of steel rebar against seawater environment (3.5% NaCl) at four temperatures; 20, 30, 40 and 50°C. The corrosion parameters and pitting probability of the carbon steel rebar were measured in separate experiments using Tafel plot and cyclic polarization procedures, respectively. The corrosion protection efficiency was increased with increasing SiO 2 content and values of 37-80% were recorded in comparison with the concrete solution free of SiO 2 NPs. The cyclic polarization voltagrams show that the SiO 2 NPs reduces the pitting area in all SiO 2 concentrations and fully stopped the pitting problem because of the chloride ions. The surface morphology of the steel rebar was examined before and after polarization using Atomic Force Microscope (AFM).

Severe damage reinforced concrete structures affected by corrosion are increasing. The study of prevention and protection technique play an important role to cope this urgent issue. Usage of different types of surface coatings on concrete/rebar are highly depend on workmanships of construction. Thus, sacrificial anodes are offered as one of the corrosion prevention technique. The discrete sacrificial anodes are comprise of zinc metal covered with a high alkalinity mortar which sacrifices itself to protect the corrosion of rebar. The key parameter of sacrificial anode in concrete is the activating mortar. It will help the overall cathodic reaction to efficiently protect reinforcing steel. Therefore, a new sacrificial anode was then accomplished in new activating mortar components. Two different activating mortar type have been established. This research investigated the performance of the new sacrificial anodes installed in the concrete prisms, slabs, and concrete water tanks in order to explore the corrosion prevention performance as per NACE [1], ISO [2] and ASTM standards [3-4]. This experimental study was tested on ASTM G109 [3], ASTM C876 [4] and small-scale water tank suffering from chloride-induced corrosion of the reinforcement. The performance of the anodes was determined at 28 days age and 365 days after installation to assure the activating time dependency for the mortar. The results of concrete prisms and slabs revealed that the anode polarized the rebar at a significant potential. For the water tank test results, two different concrete type were conducted with exposing chloride solution and assessed using close-interval potential mapping. The results showed a good agreement with enhance the structural durability.

“…Choice of the most suitable protection method depends on many factors as cost, nature of the structure, and the required level of protection. Surface coatings of steel and concrete surfaces and concrete admixtures used reduce corrosion rate are considered the most widely used direct protection techniques used [2][3][4][5][6].…”

Fiber Reinforced Plastics (FRP) sheets are widely used now in the field of repair and strengthening of reinforced concrete structures. The presence of FRP sheets on reinforced concrete surface for repair and strengthening provides some level of protection for reinforced concrete against corrosion. This kind of protection can be considered as an indirect protection because the main purpose is not for protection but for repair and strengthening. Two fibers/resin systems were considered in the experimental program; the first is glass/polyester system with one, two, and three layers of glass fibers and the second is carbon/polyester system with one layer of carbon fibers. Effectiveness of the indirect method was evaluated through comparing them with the well-known direct protection methods (coating of steel surface, coating of concrete surface, and by using concrete admixtures). A total of 16 accelerated corrosion cells were tested in order to measure the total mass loss of the reinforcing steel bars which expresses the effectiveness of all direct and indirect protection methods
