FLEXURAL TOUGHNESS OF STEEL FIBER REINFORCED CONCRETE

摘要: A relatively new procedure was used to measure the deflections in this suudy of flexural behavior steel fiber reinforced concrete (SRC). The variables investigated were type, length and volume fraction; matrix composition. results indicate that content range 50 100 lb/cu yd provides excellent ductility for normal strength concrete. has be increased about 150 lb/ cu high Hooked-end geometry better than corrugated deformed-end geometry. Fiber 1.18 2.36 in. does not have a significant effect on toughness hooked-end fibers. Ductility values are also discussed.
