dc.description.abstract	In the context of efficiency, sustainability, and life-cycle cost, reinforcement durability became a significant concern. Long-term costs are bringing the attention of many countries and companies who aim to minimize them maximally. Subsequently, researchers started concentrating on the study of the durability of materials to enhance the sustainability and resiliency of future structures. The primary objective of this study is to examine the durability and performance of concrete beams reinforced with different types of materials exposed to identical environmental conditions and loads. Therefore, several types of corrosion-resistant reinforcing rebars including Fibre Reinforced Polymer (FRP) (Glass, Carbon, and Basalt), Martensitic Micro-Composite Formable Steel (MMFX), and Stainless steel, in addition to the conventional uncoated black steel for comparison purposes were examined. The research studied the performance of 28 beams in total, the beams were 2 metres long with 150x305 mm cross section, twenty-one beams were subjected to environmental conditions, and seven were used as controls. The exposed beams were subjected to a sustained load equivalent to 40% of their ultimate capacity, exposed to spraying salt water with 3.5% sodium chloride (NaCl) concentration, and subjected to a total of 195 freeze-thaw cycles with temperature ranging between +34°C and –34°C equivalent to 5 years in real conditions. After the exposure, the beams were acclimatized to room temperature and together with the control unexposed specimens were tested for ultimate capacity. No one material was found to be superior in all of the studied parameters, the beams presented differences in the performance such as load-deflection, deviation from linearity, ductility, crack pattern, in addition to the strength loss, and cost. The initial cost of the beams was calculated, and the results showed more than 60% difference for specific types of rebars in comparison to conventional steel reinforced beams.	en_US
