“…Carbon steel is easily fabricated, protect biodiesel from exposure to sunlight, and its price is cheaper than stainless steel (Groysman, 2014; Komariah et al, 2017; Restrepo-Florez et al, 2014). However, carbon steel has a weakness that is easily corroded, either chemically or by microorganisms because stainless steel has more protective action of chromium and nickel elements (Heyer et al, 2013;Adebayo et al, 2014;Kovács et al, 2015). Corrosion is an interaction reaction between the metal and its environment, occurs because of the tendency of the metal to return to its original condition, the oxidant state in nature (Zarasvand and Rai, 2014; Beech and Sunner, 2004).…”

This study focused in the effect of water content on biofilm and bio-corrosion, and knowing its influence on biodiesel-diesel blends’ quality. Biodiesel is hygroscopic and less stable, makes this fuel needs more attention in storing. Fuel is usually stored in a storage tank of carbon steel which easily corroded by microorganisms, such as Bacillus megaterium. Corrosion occurs because microorganisms use fuel as nutrients and water content in hygroscopic biodiesel supports to grow and metabolize. Experiments were carried out by immersing carbon steel in medium 30% biodiesel (B30) for 21 days with water content variation of 0%, 5%, and 10% volume. The number of colonies in biofilms increased up to 1,3 times in a 10% water content. A uniform biofilm provides an inhibitory effect on corrosion per time, also layer of iron phosphate formed on water content variation, so the highest 0.642 ± 0.28 mm/year on 0% water content. Fe2O3, Fe3O4, and FeOOH are the corrosion product by Bacillus megaterium. The highest biodegradation efficiency achieved by variation water content both 5% and 10% were 68.5% and 67.23%, and then followed by no water content at 60.40%.

A Review on Corrosion in Concrete Structure: Inhibiting Admixtures and Their Compatibility in Concrete

et al. 2021

View full text Add to dashboard Cite

The development in marine industry and its effort in building bridges has placed a huge demand on reliability and duration of service of reinforcing steel in concrete. Literature has documented several studies on corrosion of reinforcing steel in concrete induced via carbonation and chloride in marine milieus. Extension of concrete structures service life has been one of the foremost strong worries of the concrete industry, especially for marine industry. Hence, the necessity to employ a cost effect system for shielding the reinforced steel in concrete from corrosion. Studies have shown that one prospective solution in combating corrosion deterioration in reinforced steel in concrete structures is the introduction of corrosion-inhibiting admixtures into concrete. This review discussed at length corrosion in reinforced concrete and corrosion inhibitors in relation to concrete together with the classification of inhibitors based on the method of applications. This review further reports corrosion-inhibiting admixtures in concrete. As a result, the aspects of corrosion inhibitors this manuscript reviewed are corrosion inhibitors employed as admixtures in concrete for new construction in the marine industry. Furthermore, corrosion inhibitors are employed for repairs and maintenances admixed with concrete for patches on marine structures, squirted onto the surface of the concrete or put on the concrete surface via saturation treatment. As a result of the excellent properties of functional nanostructured materials, the advancement in the implementation of functional materials in inhibiting admixtures in concrete is fast growing in marine industry. Hence, the Integration of functional materials in inhibiting admixture and their compatibility were reviewed. The significance of inhibitors employed as admixtures in concrete for practical applications of corrosion are the suppression or mitigation of corrosion process of metals used in marine industry and the patches of already constructed structures. The current problems related to corrosion-inhibiting admixtures in concrete and the future research and development directions were discussed.

In the present study, the main influencing factors of crystallization fouling in electric water heating were investigated. Dependence on the saturation index and four operating parameters was analyzed, namely: liquid temperature, surface temperature, flow rate and electrical leakage current. A focus of the study was the influence of electrical leakage current on the fouling behavior and the morphology of the deposited crystal layers. The investigation shows that the aforementioned parameters influence the fouling process and crystal size growth in a different way. The experimental results were used to find a correlation between the electrical leakage current and induction time. In addition, a modeling approach is presented which allows an estimation of the fouling mass flux.
