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 for a very high strength matrix of an average compressive strength of 85 MPa.
Control, single, two-fiber and three-fiber hybrid composites were cast using different fiber types such as macro and micro-fibers of steel, polypropylene and carbon.
Flexural toughness tests were performed and results were extensively analyzed to identify synergy, if any, associated with various fiber combinations.
Based on various analysis schemes, the paper identifies fiber combinations that demonstrate maximum synergy in terms of flexural toughness.
