Abstract
This study investigates the effect of macro-synthetic polypropylene fibers on the shear strength and failure behavior of longitudinally reinforced concrete beams with and/ or without transverse reinforcement. Eight large-scale were constructed, cured and tested at Civil Engineering Laboratory Building (CELB). This includes flexural reinforced concrete beams without transverse reinforcement (RC), reinforced concrete beam with minimum transverse reinforcement (RCS), 0.5% volume macro-synthetic polypropylene fiber-reinforced concrete beams without stirrups (SNFRC 0.5%), and 0.75% macro-synthetic polypropylene-fiber reinforced concrete beams without stirrups (SNFRC 0.75%). During production of large-scale beams, 19 Cylinders and 9 small-scale beams were produced from the same mix-design and cured for testing. Cylinders of 4 inch diameter and 8 inch height, were tested after 28 days curing using ASTM C496 and ASTM C39 standards. Likewise, small-scale beams of 6 inch by 6 inch by 20 inch were produced and tested using ASTM C1609. This study reports on the increased shear strength performance of large-scale beams due to the application of 0.5% and 0.75% macro-synthetic polypropylene fibers into the concrete matrix.
