Service Life Prediction of Concretes Incorporated with Fly Ash and Alccofine with respect to Chloride Ion Penetration
Abstract: Chloride-induced corrosion poses a significant threat to the degradation of reinforced concrete structures, especially in extreme environments such as marine and industrial exposure conditions, where the damage can be particularly severe. This study provides an experimental investigation utilizing three distinct water-binder ratios (0.3, 0.4, and 0.5) applied to three types of concrete mixtures: conventional concrete, concrete blended with 40% fly ash, and concrete blended with 40% fly ash and 2% …

Service Life Prediction of Concretes Incorporated with Ground Granulated Blast Furnace Slag and Icrete with respect to Chloride Ion Penetration
Abstract: The reduced service life of concrete structures in coastal or de-icing salt conditions is commonly attributed to corrosion generated by chloride. Therefore, extensive research is being conducted to estimate the time taken for threshold chloride ions to reach the reinforcement and break the protective layer, initiating the corrosive process. This study conducted an experimental investigation on controlled concrete, concrete incorporating 50% GGBS, and concrete incorporating both 50% GGBS and 2% …

Experimental Investigation on Strength and Durability Properties of Slag Based Alkali Activated Concrete Incorporating Fly Ash
Abstract: To minimize carbon emissions during cement production and to resolve landfill issues arising from industrial waste, the adoption of alkali-activated concrete (AAC) incorporating various by-products from industry has become increasingly popular as environmentally friendly option to conventional concrete in the construction sector. This study focused on strength and durability of AAC by utilizing waste industrial by-products such as ground granulated blast furnace slag (GGBS) and fly ash (FA) at ambient …

Service Life Enhancement: Exploring the Effects of Supplementary Cementitious Materials on RC Structures in Marine and Urban Contexts
Abstract: Reinforced concrete (RC) structures stand as the cornerstone of modern construction due to their cost-effectiveness and widespread availability. The most predeterminant factor for the deterioration of RC structure is due to the corrosion of reinforcement. This review paper comprehensively explores the occurrence and degradation mechanism of reinforced concrete (RC) structures when exposed to adverse environmental conditions, i.e., marine, or urban environments. Corrosion of reinforcement takes place when RC structures are …

Polymeric Coating Applied for Corrosion Protection of Mild Steel in Corrosive Medium
Abstract: Mild steel is coated with a polymer layer of polybutadiene for protection. However, this coating does not effectively safeguard the metal in environments containing moisture, sulphur dioxide, or chloride. These pollutants interact with the polybutadiene-coated surface, creating a highly corrosive atmosphere. Moisture condenses on the coated metal surface and absorbs sulphur dioxide, forming sulphuric acid. This acid initiates both chemical and electrochemical reactions with the polymer-coated metal, accelerating the corrosion …
