Nano-Engineered High Performance Concrete For Improved Chloride Resistance In Marine Structures

Abstract

Marine structures are highly susceptible to chloride-induced corrosion, severely affecting their service life and safety. This study investigates the development and performance of Nano-Engineered High Performance Concrete (NEHPC) incorporating nano-silica and graphene oxide to enhance chloride resistance. The paper evaluates mechanical strength, microstructure, and permeability properties, supported by durability tests including Rapid Chloride Penetration Test (RCPT), water absorption, and microstructural analysis using SEM-EDX. The results indicate a significant improvement in resistance to chloride ingress and an enhancement in compressive strength, making NEHPC a promising solution for durable marine construction.
