Abstract
This study explores the feasibility of partially substituting conventional cement in concrete with steel and polypropylene fibers to improve mechanical performance and introduce alternative composite materials. Concrete cube specimens measuring 150 × 150 × 150 mm were cast with varying mix designs corresponding to M20 and M25 grades. The experimental program was executed in two distinct phases. In Phase I, control mixes of M20 and M25 grade concrete were prepared using conventional cement. In Phase II, cement was partially replaced by steel and polypropylene fibers at 0.5% and 1.0% by weight of cement for each grade. Compressive strength tests were conducted on the specimens at 7, 14, and 28 days of curing under ambient conditions. The results demonstrated an incremental improvement in compressive strength with increasing fibre content up to 1.0% replacement, followed by a decline at higher percentages. The peak compressive strength was recorded at 1.0% fibre content for both M20 and M25 grades. The findings suggest that partial replacement of cement with steel and polypropylene fibers at 0.5% to 1.0% enhances compressive strength, whereas exceeding this threshold adversely affects performance.
