Study Effect of Optimized Hybrid Fiber on the Strength Characteristics and Structural Performance of the Concrete

Hybridization is a process by which two or more kinds of fiber are blended appropriately so as to produce hybrid fiber. Hybrid fibers when inducted in concrete add greater value to the concrete. The selection of hybrid fiber is based on fiber response, fiber dimension, and fiber function. A combination of long fiber and short fiber enhances the ductility of concrete to a greater extent by way of reducing the formation of micro cracks and macro cracks in the concrete. Short fibers bridge the micro cracks and thereby increase the tensile strength of concrete. Long fibers block the propagation of macro cracks and thereby increase the tensile strength of concrete. In accordance with fiber constitute response, one type of fiber should be stronger and stiffer to meet the first crack stress and improve the ultimate strength of concrete, whereas the second type of fiber should be more flexible and ductile to improve the toughness and strain capacity in the post crack zone.
