The The Resistance of Fiber-reinforced Concrete with Steel Fibers and CFRP to Drop-weight Impact

In this paper, the effects of macro-synthetic steel fibers and bidirectional carbon fiber-reinforced polymers (CFRPs) on impact resistance concrete specimens were studied. 54 cylindrical with different compressive strengths (20, 30, 40 MPa) fiber content ratios (0 %, 1 1.5 2 %) tested under loading. Half these CFRP wrapping. The subjected to weight (46.7 66.8 kg) dropping at a height 1.62 m. process was continued until 30 % loss in observed number droppings related recorded. Results indicated that (corresponding droppings) increased by using or wrapping, separately. However, results demonstrated wrapped sheets had much further than FRCs without Finally, showed greater concrete, better resistance.
