ASSESSMENT OF STATISTICAL VARIATIONS IN IMPACT RESISTANCE OF HIGH-STRENGTH CONCRETE AND HIGH-STRENGTH STEEL FIBER-REINFORCED CONCRETE
High-strength concrete is the term used for concrete that has a compressive strength of over 42 MPa (6000 psi). This article reports on a study in which the impact resistance variations of high-strength steel fiber-reinforced concrete (HSFRC) were compared to those of high-strength concrete (HSC). The results showed that the impact resistance of the high-strength steel fiber-reinforced concrete improved satisfactorily over that of the high-strength concrete; the failure strength improved most, followed by first-crack strength and percentage increase in the number of post-first-crack blows. The authors developed failure strength regression models for both concretes, and then established the accompanying 95% prediction intervals for the strength. These two regression models enabled point and interval estimates for the number of blows to ultimate failure in the concretes.
