Abstract

Abstract Existing concrete buildings are always in need of repair or renovation as they are getting older, carrying more weight, or needing to be redesigned. The most common materials used to strengthen concrete structures are ferrocement, fiber-reinforced polymer, engineered cementitious composite, and ultra-high-performance concrete. However, there are some other methods and materials that can be used as well. There are pros and cons to every composite material that is unique to it. Each material works very well in certain situations and is known around the world for being able to be used in a wide range of situations. This paper gives a brief overview of several cement-based strengthening materials that have shown very promising results when used to repair older structures. This review looks at certain factors, such as how to retrofit a structure for bending, shear, and confinement. In conclusion, more studies should be done to come up with flexible industry standards for the use of cementitious materials to strengthen structures made of reinforced concrete.
