The effect of iron chip additive on structural behavior of under-reinforced and over-reinforced cantilever beams

Abstract

This study focused on whether industrial iron chips waste can be recycled by using them in the production of reinforced concrete cantilever beams. The amount of aggregate in the range of 0-4 mm in the concrete used in the production of cantilever beams was determined. And this amount was reduced by 10%, 20%, and 40% and replaced with iron chips. Cantilever beams have been produced in two different ways as under-reinforcement and over-reinforcement by changing the diameters of the tension reinforcement. Thanks to the experimental setup, the cantilever beams were loaded at their endpoints. In the experimental study, the load-displacement curves of the cantilever beams were obtained. According to the findings obtained in the study, under-reinforced cantilever beams behaved more ductile than over-reinforced cantilever beams. Cantilever beams with 40% iron chip additive reached the highest strength and exhibited the most brittle fracture examples. Cantilever beams containing 10% and 20% iron chip additives increased their ductility values up to 14.54% and decreased ​​their strength up to %17.27 compared to reference cantilever beams.
