Abstract: In most cases, Fiber Reinforced Concrete (FRC) contains only one type of fiber. The use of two or more types of fibers in a suitable combination may potentially not only improve the overall properties of concrete, but may also result in performance synergy. The combining of fibers, often called hybridization, is investigated in this paper under three modes of load application: quasi-static flexure, quasi static shear and impact. Control, single-fiber and two-fiber hybrid composites were cast using diverse combinations of two types of macro steel and one type of micro-cellulose fibers. Flexural, shear and impact tests were performed and results were analyzed to identify synergy, if any, associated with various fiber combinations. The paper identifies fiber combinations that demonstrate maximum synergy under flexure, shear and impact.
