Evaluation of the Effectiveness of Engineered Cementitious Composite (ECC) for Repairing Distressed Reinforced Concrete Beams: Literature Survey

Abstract

This paper presents a literature survey that evaluates the effectiveness of using Engineered Cementitious Composite (ECC) for repairing distressed reinforced concrete (RC) beams. The study aims to provide a comprehensive analysis of existing research studies and their findings regarding the application of ECC in the repair and strengthening of distressed RC beams. The literature survey begins by discussing the common causes of distress in RC beams, including corrosion, excessive loading, and structural deterioration. It then explores the advantages and limitations of using ECC as a repair material for distressed beams. ECC is known for its unique properties, such as strain hardening behavior, enhanced ductility, and improved crack control. The survey critically examines various experimental and analytical studies conducted on the effectiveness of ECC in repairing distressed RC beams. The reviewed studies analyze parameters such as load-carrying capacity, deflection, crack width, and durability performance after the application of ECC. The findings of the literature survey indicate that ECC can significantly enhance the structural performance of distressed RC beams. It leads to increased load-carrying capacity, reduced deflection, improved crack resistance, and enhanced durability. The literature survey serves as a valuable reference for researchers, engineers, and practitioners involved in structural rehabilitation and repair projects. It provides insights into the key factors influencing the effectiveness of ECC and offers guidance for the optimal utilization of this innovative material in achieving successful and durable repairs of distressed RC beams.
