Penetration resistance of ordinary concrete and the steel fiber reinforced concrete mixed with high hardness aggregate was evaluated by using more widely experience, the semi-empirical formula, and the application range and limitations of the formulas were analyzed. The revisional ACE formula is put forward by introducing the hardness of aggregate and toughness index of steel fiber reinforced concrete. Calculation result with revisional formula was in good agreement with test result, which verified the rationality of the revisional ACE formula of concrete.
Key words
