Abstract |
|
Impact resistance of M60 grade high strength concrete (HSC) and high strength steel fiber reinforced concrete (HSFRC) with fiber volume fraction (Vf) of 0.5, 1, 1.5, 2 % is investigated by using drop weight test method as recommended by ACI Committee 544. Due to non-availability of standard drop weight test equipment in India. Fabricated drop weight equipment is used. The obtained results from drop weight test suggest that addition of steel fibers in concrete at 0.5% Vf shows decrease in first crack impact resistance in comparison to HSC of same strength. While it shows some increase for first crack impact resistance than HSC at steel fiber Vf of 1.5% followed by 2 and 1 %. HSFRC showed good increase in ultimate failure impact resistance for various steel fibers Vf. It continuously improved as steel fiber Vf in concrete increases. |
