Abstract: The combination of one kind of fibers with another kind of fibers or one length with another length of fiber is termed as hybrid fiber. Mixing of different lengths of fiber in concrete is known as graded fiber. According to different research articles short fibers are unable to transfer force due to insufficient grip length, fibers more than critical length fail in snapping of fiber. Short length Fibers up to certain range increase toughness and bridge the micro cracks. Long fibers arrest macro cracks, resistance to post peak deformation. The M25 grade of concrete was chosen with a continual w/c ratio 0.43 where fractional replacement of Ordinary Portland Cement with glass fiber is done in different proportion. After preparing the samples according to Taguchi’s method orthogonal array, the mechanical characterizations are performed. Hardened concrete tests have been piloted to evaluate the mechanical properties of M25 grade of concrete. Weighted Aggregated Sum Product Assessment (WASPAS) method is utilized for optimization of input variables. In order to outline comparative consequence of measured criteria a pairwise comparison matrix was used. The results of all tests were analyzed, comparison has done among concrete mixes and the conclusion is drawn.
