The effect of metallic and non-metallic fiber on the mechanical properties of waste ceramic concrete

Academic Article

Abstract

  • Fiber-reinforced concrete has widely been used due to its advantage that it excels over plain concrete. The present study highlights the metallic and non-metallic fiber effect in varying percentages on waste ceramic optimal concrete (WOC) mechanical behavior. WOC has been obtained by replacing plain M25 grade concrete constituent with ceramic constituent (20% ceramic aggregate, 10% ceramic sand, and 10% ceramic powder) on the basis of compressive, tensile, flexural, and combined (flexure and torsion) strength test performed in the laboratory. Two types of metallic fibers, namely hooked-end steel fiber (HK) and crimped steel fiber (CR), and two types of non-metallic fibers, namely polyvinyl alcohol fiber (PVA) and polypropylene fiber (PP), have been used. Based on the total concrete volume, two fiber fractions of 1% and 2% were added to the specimen. Overall, 108 samples were cast for testing in compression on cube, tension on cylinder, flexure on beam, and combined (flexure and torsion) on the beam. For each test and each percentage, three samples were cast. Encouraging results have been obtained for both metallic and non-metallic fibers. In metallic fiber-WOC, optimal increment with respect to plain WOC in compression, tension, flexure, and combined (flexure and torsion) has been found 3.64%, 85.56%, 92.59%, and 85.18%, respectively, for 2% CR fiber wherein, for non-metallic case, the increment was obtained as 5.52%, 30.59%, 9.62%, and 9.09%, respectively, for 1% PVA fiber.
