Individual Comparison and Joint Evaluation of Fiber Reinforced Polymers (FRP) and Ultra High Performance Fiber Reinforced Concrete Used to Retrofit Structures

Abstract

This dissertation is a rigorous investigation that studies two important essential materials in construction: Polymer Fiber Reinforced (FRP) and Ultra-High-Performance Fiber Reinforced Concrete (UHPFRC), and their applications for strengthening and rehabilitation. Hence, this study exposes and describes the history, characteristics, types, laboratory tests, and applications of these materials by collecting data from previously published works. Then, a deep comparison of the features of these materials and especially an evaluation of the possibility to use these together to reinforce structures and for structures rehabilitation are assessed. On the other hand, these materials have been studied in the last years because they fulfilled in the last years because they fulfill the high quality and performance demanded in construction. Therefore, it’s clear that one of the most important aspects of FRP and UHPFRC is their high strength and ductility (in the UHPFRC case), so it is interesting to compare them and even more evaluate them if it’s possible to use them together. However, there are some minima negative aspects like the high cost. Hence, there are multiple studies focused on finding materials that could partially replace UHPFRC high-cost components, such as cement, silica fume, and superplasticizer. To this end, these investigations evaluate economical materials even better if there are recycled. Sequent, knowing the importance of sustainability and economy in constructions, it will be important to review that.
