Fire Resistance and Durability of Concrete Buildings Strengthened with FRP Sheets aoReview Analysisa
Sustainability is the way or the method to improve the human life by using the natural resources. There are three basic aspects of the sustainability which are; Social aspect, Economical aspect, and Environmental aspect. As result of that, civil engineers now days try to find new materials and methods to reach and apply the sustainability concept. For example, in the materials aspect, there are many ingredients such as Fibers, polymers, lightweight aggregates, fly ash, and slice fume were added in the concrete mix to have better durability. Concrete is one of the most commonly used materials in building construction projects. Many scientists and professionals continue to find new ways to improve the strength of concrete material and reduce its weight/volume ratio to the preserve natural materials and reduce energy. One of the most important factors in concrete structures is the stability of the structure against external forces such as earthquakes, wind loads, fires and etc. The Fiber Reinforced Polymers (FRP) sheets are externally bonded to the concrete surfaces to enhance the performance of the concrete structures. Several studies were conducted to investigate the compressive strength of the concrete that wrapped with FRP composite when they are exposed to harsh environment factors such as elevated temperature, freeze-thaw cycles, high humidity and etc. However, there are many studies which cover and study the effects of the extreme conditions at concretes wrapped with FRP which could help the engineers in the future to avoid fatal results such as structures failures. The main goal of this paper is to collect information about durability and fire resistance of concretes wrapped with FRP polymers and that will be done by reviewing different journals which cover these points. The experimental programs of the journals will be explained and supported by the figures.
