Abstract

Self-compacting concrete is used as critical reinforced areas such as Beam-Column joints, Bridge decks, Post/ Pre-stressed concrete structures, and some industries because of their self-consolidation and proceeds more advantages like labor reduction, speed of construction, safe method, structural, ease of erection, and reduces the compaction time. The flexural behaviour of reinforced concrete beams/ slabs was determined for their tensile and ductility characteristics. The tensile behaviour of concrete was developed by embedding reinforcements, the addition of fibers, etc. In the present research, the novelty was brought in SCC by replacing the mono-steel fibers using stainless steel scrap obtained from the lathe waste of industry. For the preparation of greener SCC as a construction material, the cement was replaced by 30% of GGBS for all mixes. Here, the addition of steel fibers used in SCC volume was in the range from 0% to 2% with an increment of 0.5% and was replaced by the stainless steel scrap of constant 0.125% from the industrial lathe waste. SCC’s fresh and mechanical properties were investigated separately for both mono-steel fibers and hybridized fibers with stainless steel scrap. It was inferred that the SCC mix containing steel fibers of 1.5% when replaced by 0.125% of stainless steel scrap in the hybridized formulation of fibers has performed better tensile strength characteristics among other SCC mixes.
