Abstract
Abstract
Adding steel fibres can transform the brittle characteristic of concrete into a ductile state. The objective of the current study is to test the impact resistance of macro and micro steel fibre-reinforced self-compacting concrete (SFRSCC) experimentally by applying a simulated drop-weight impact, as well as statistically and through reliability studies. Cube specimens were used for the experiment. The inclusion of macro and micro steel fibre (SF) greatly increased the concrete mixture’s impact resistance. All the concrete samples exhibited the same failure pattern. Using Response Surface Methodology (RSM), the impact resistance of SFRSCC mixtures can be accurately predicted. The first and failure cracks (N1 and N2) follow a two-parameter Weibull distribution (WD) function of drop-weight impact test.
