ARTICLE ANNOTATION

quote
This study is focused on the evaluation of the physical, mechanical, and corrosion properties of recycled reinforcement steel (RRS) extracted from dismantled reinforced concrete bridge structures. The chemical composition and tensile strength characteristics of A400-grade reinforcement were analyzed in accordance with current standards. The results show that the yield strength of the recycled reinforcement ranges from 340 to 370 MPa, while the ultimate tensile strength varies between 480 and 520 MPa. Corrosion damage is mainly superficial, with a depth of 0.05–0.2 mm. The obtained results scientifically substantiate the feasibility of reusing recycled reinforcement steel with the application of reduction factors in secondary and non-load-bearing structural elements of bridge foundations.
