Doctoral Dissertation at the University of Basrah Examines the Effect of Adding Hematite Powder on Torsional Behavior
A doctoral dissertation at the College of Engineering, University of Basrah, examined the effect of adding hematite powder on the torsional behavior of high-strength, fiber-reinforced concrete members.
The dissertation, submitted by PhD candidate Mohammed Saber Abdul Hassan, aimed to determine the optimal percentage of hematite powder that provides maximum torsional resistance under pure torsion loading, as well as to identify the optimal percentage and shape of steel fibers that achieve the best torsional performance.
The dissertation comprised five chapters, through which the researcher discussed how the addition of steel fibers enhances the initial cracking torque and the ultimate torsional strength, in addition to improving the overall properties of concrete.
