Low-Velocity Impact Behaviour of Novel Steel Fibrous Grouted Aggregate Concrete
This investigation explores the impact behaviour of novel steel fibrous grouted aggregate concrete (SFGAC) subjected to falling mass impact. The making of SFGAC comprises high fibre and coarse aggregate content with respect to conventional fibre-reinforced concrete (CFRC). Initially, the steel fibres and coarse aggregates were thoroughly mixed and filled into the moulds; subsequently, a cement slurry injection is prepared with cement, fine aggregate and water. All samples were tested using drop mass impact in conformity with ACI Committee 544. Ten concrete mixes were formulated with 3D and 5D hooked end steel fibres, where fibre content differs between 1.0% and 5% for CFRC and SFGAC. The number of blows to induce crack initiation and ultimate crack, energy absorption capability at crack initiation and ultimate crack, failure patterns and compressive strength are examined and conferred. The result shows that the specimen with SFGAC attained better impact strength than the CFRC specimen. Consequently, based on the annotations, a novel SFGAC is a tough competitor for various applications owing to effortlessness production technique with higher impact strength.
