Torsion behavior of reinforced standard strength concrete beams using ceramic waste powder

Abstract The study aims at the utilization of ceramic insulator manufacturing industry waste in standard strength concrete (SSC) for infrastructural applications which addresses the Sustainable Development Goal (SDG‐11). The ceramic waste powder (CWP) from the electrical insulator industry has been used in the present study. From the x‐ray fluorescence analysis, it was found that the ceramic electrical insulator waste powder shows a significant increase in pozzolanic chemical composition. As many studies have been done on the mechanical and durability properties of concrete using CWP, the focus on the torsion resistance of ceramic waste reinforced standard strength concrete (RSSC) beams has not been thoroughly examined. In this study, six beams of 1.50 m span were cast and tested using the Materials Testing System loading frame. The ultimate torsional moment, angle of twist, torsional stiffness, curvature ductility and fracture width of each beam specimen were evaluated and compared. The experimentally found ultimate torque was compared theoretically using a space truss analogy and IS 456‐2000. The average increase in ultimate torsional moment and curvature ductility of ceramic waste RSSC beams was found to be 23.35% and 4.50%, respectively, when compared with the control RSSC.
