Through the mechanical property tests of 234 samples,the effects of types,volume fractions and aspect ratios
 of steel fiber as well as cement matrix strength on the compressive strength,splitting tensile strength and
 flexural toughness of steel fiber reinforced concretes(SFRC) were investigated.The results showed that steel
 fiber had limited impact on the compressive strength,but altered the compressive failure pattern of concretes.
The splitting tensile strength and flexural toughness of concretes were improved obviously by the increase of
 volume fraction of steel fiber.The improvement of steelwire-cut steel fiber was the best,the greater the aspect
 ratio was,the more obvious of the improvement appeared.

Key words: steel fiber volume fraction; steel fiber types; steel fiber ratio; strength; toughness
