- Abstract
- In most cases, Fiber Reinforced Concrete (FRC) contains only one type of fiber. However, 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 process of combining two or more fibers, often called hybridization, is investigated in this paper under quasi-static flexure and impact flexure conditions. Besides a reference plain mix, single-fiber and two-fiber hybrid composites were cast using diverse combinations of two types of macro-steel fibers and a micro-cellulose fiber. Quasi-static and impact flexural tests were performed and the results were analyzed to identify synergy, if any, associated with various fiber combinations. The paper identifies fiber combinations that demonstrate maximum synergy under impact.
