The fine aggregate (M-Sand) is substituted by varying the waste glass powder as 0 percent, 5 percent, 10 percent, 15 percent, 20 percent, 25 percent, 30 percent, 35 percent, 40 percent, 45 percent, and 50 percent, and the mixture is cured under atmospheric curing. The impact of the WGP weight percentage on the flexural behavior of GPC beams is analyzed. The conduct of RGPC beams varies from that of ordinary Portland Concrete (OPC) beams, which is defined and examined. Deflection, ductility factor, flexural strength, and toughness index were measured as flexural properties for beams. In contrast to the reference beams, the RGPC beams containing 50% Waste Glass Powder as fine aggregate demonstrated a major increase in cracking resistance, serviceabi...

A total of 24 simply supported reinforced concrete beams, with Hybrid Ferro Fiber Concrete (HFFC) at critical sections were tested in flexure. The tension reinforcement in the beams was varied to give two types of basic behavior viz., under reinforced and over reinforced. The Hybrid Ferro Fiber Concrete at critical sections of all category beams enabled the reinforced concrete sections to fail in ductile manner.

Such concrete composite can be termed as ENGINEERED FERRO FIBER CONCRETE (EFFC). This paper presents an experimental investigation on the behavior of EFFC under axial compression. The main variable considered in this study was specific surface factor (S f) of ferrocement shell. A total of 60 prism specimens of size 150mmX150mmX300mm were tested under strain control rate of loading. The results indicated that the combined use of ferrocement and fibers has improved the ultimate strength; strain at ultimate strength and the ductility. The improvement is proportional to the specific surface factor (S f) of ferrocement shell for a given confinement index (C i) of lateral reinforcement and reinforcing index (RI) of steel fiber reinforced concrete. The ductility potential of EFFC is highlighted.
