Experimental investigation on steel fiber reinforced concrete with partial replacement of fine aggregate by copper slag
In many developing countries, concrete is the most extensively used "manmade" material for construction in all types of civil engineering projects. Concrete is also an environmentally friendly material, which is more important in locations where environmental awareness is expanding. Researchers have been attempting to increase the quality, strength, and durability of materials against adverse exposures for decades. Concrete made of Portland cement is regarded to be a fragile substance. Unreinforced concrete cracks and fails when subjected to tensile pressures. Steel reinforcement has been utilized to solve this problem since the mid-nineteenth century. The reinforcing steel is expected to carry all tensile loads in a composite system. When fibers are added to the concrete mix, the composite system's tensile load capacity is increased as well. In reality, research has shown that fiber reinforcing can improve the final strength of concrete. The goal of this study article is to employ solely fibers. On 150x150x150mm cube and 150mmx300mm cylindrical specimens, the experimental investigation consisted of casting and compression testing using a test method that gave the complete compressive strength, split tensile test with and without steel fiber of volume fractions 0,1, and 1.5, percent of 0.75mm diameter of the aspect ratio of 80 on ordinary Portland cement concrete and replacing fine aggregate with copper slag of 40% and 60%. Based on the findings, higher crack resistance and improved tensile strength will be discovered. At 7 days, 21 days, and 28 days after curing, the proposed sample will be analyzed. These findings will reveal if the FRC is suitable for proper confinement in structures subjected to high loads such as seismic and impact loads.
