Abstract

This technical research paper deals with the study on the impact strength behavior of steel fiber reinforced self-compacting concrete (SFRSCC) with a triple blended technique. The triple blended means the partial replacement of cement by Fly ash (FA) and condensed silica fume (CSF) by mass. The replacement of cement by FA and CSF were 20and 10 percentages respectively to fulfill the rheological requirements of the Self-compacting concrete (SCC). Steel fibers having 1 mm diameter, 20, 30, and 40 as aspect ratios are used. The steel fibres are added to the volume of the concrete were at 0%, 0.2%, 0.4%, 0.6% and 0.8%. From which the result benefits of the impact strength are studied. The specimens are tested for impact as per ACI specifications. The regression equation is carried out based on experimental values. A mathematical model developed and verified the validity of the equation from the experimental results.
