EFFICIENCY OF REHABILITATION TECHNIQUES AND PRODUCTS IN REINFORCED CONCRETE STRUCTURES - A BIBLIOGRAPHICAL REVIEW

Abstract

Reinforced concrete is the most used construction material in the world due to its advantages such as its relatively low cost, the ease of obtaining the components, its durability when dosed correctly, its adaptability to different formats, among others. However, over time and exposure to the environment, these structures are subject to various types of damage that threaten their integrity and safety. There are several techniques and products developed for the rehabilitation of reinforced concrete structures. In this context, this work aims to identify the main rehabilitation techniques and products in reinforced concrete structures, as well as their advantages and possible limitations. Bibliographic research was carried out using the keywords: Armed. Concrete. Products. Rehabilitation. Techniques, in the Scielo and Google Scholar databases. The results indicate that among the most used techniques and products, Fiber Reinforced Polymeric Composites (CPRF) stand out, mainly carbon fiber composites (CFRP). CFRP has some advantages over traditional reinforcement elements such as ease of application, low density, high tensile strength and anti-corrosion properties. It is important to know the degradation mechanisms of reinforced concrete structures to obtain a correct diagnosis.
