There has been research into the flexural behaviour of composite beams with a variety of fibre layer depths, all of which were designed using the balancing section and the limit state design idea. The fibre depth is estimated to be 112 mm (d = 112 mm), with the first three dimensions being 94.44 mm (d1 = 94.44 mm), 46.12 mm (d2 = 22.35 mm), and 22.35 mm (d3) respectively. The percentage of fibre in the cement might vary from 0.28% to 0.50% to 0.70% to 1% depending on the depth. Compression and tensile tests have been conducted on both the cube and cylinder portions of the beam specimen. For example, brittle failure is seen in beam specimens comprised completely of Steel fibres and no Mild Steel (M.S) bars. Reinforced with steel fibre and demolition debris, concrete can withstand micro-cracks, cavitations, and other flaws with ease (DW). Fibre-rich waste items might be utilised to create a suitable replacement. Its extreme dispersion creates additional challenges for specialised production. Due to cavitations, the interconnectivity of the particles is weakened, and the concrete’s stress zone becomes more transparent. Waste materials such as fibre and river bed material (RBM) may assist address this deficiency by filling in the spaces between the coarse aggregates. An experimental study was done on both fresh and cured concrete with a notional mix of 1:1:3 by weight and a water-to-cement ratio of 0.5:1 in order to achieve the necessary mean strength as defined by Indian Standard 456:2000. Researchers have undertaken trials to evaluate the strength and durability of RBM (3 mm–4.80 mm), demolished rubbish (13.5 mm–22 mm), and fibre (FRC) to that of standard concrete. The results show that fibre addition improves concrete binding abilities and micro crack control makes the material more adaptable. These investigations show that the inclusion of 0.5% fibre greatly improves the mechanical features of FRC in comparison to RC in the stress zone.
