Abstract

Concrete has a low tensile strength, limited fatigue life and is characterized by brittle failure resulting in almost complete loss of loading capacity. Different types of fiber are added to concrete mixes to improve their performance in both a fresh and a hardened state. The use of single and hybrid fibers in plain concrete is increasing and more studies are needed to improve the properties of concrete especially subjected to strong fraction like airport floors. The hybridization of different types of fibers may play important roles in arresting cracks and thus achieve high performance of concrete. Therefore, this study was conducted to investigate the use of different percentages of fibers in high strength concrete and investigates the optimization of concrete reinforced with different percentages of steel fiber S (0% to 1%), glass fibers G (0.0% to 0.094%), basalt fiber B (0.0% to 0.5%). Also, hybridization of steel fiber and glass fibers, steel fiber and basalt fiber as 1% volumetric fractions (80% + 20%), (70% + 30%) and (60% + 40%) were investigated. The slump value, permeability, compressive strength, tensile strength, and flexural strength are determined. As well as abrasion resistance and water absorption are also measured. The fiber percentage is adjusted to alter the brittle failure. The results shown that addition of fibers to concrete mixture decreases both the slump and abrasion, while increases permeability, compressive and tensile strength.
