Degradation of Reinforced Concrete Beams Subjected to Sustained Loading and Multi-Environmental Factors

In the process of service, reinforced concrete structures have to bear both load and multi-environmental factors. The deterioration beams is critical durability, safety, sustainability structures. main aim present research determine degradation mechanism subjected sustained loading Reinforced beam specimens were prepared, loaded then exerted At end each period, (chemical contents surfaces, carbonation depth, compressive strength maximum cracks) corrosion steel bars (corrosion ratio tensile strength) continuously measured. Moreover, degraded flexural in four-point bending failure tests. factors was analyzed. Thus, this study can promote a comprehensive understanding
