Influence of Recycled Aggregate and Steel Fiber on the Compressive Strength of Concrete: A Comparative Study of NAC and RAC MixesBy Bharti Ahirwar, Harsh Rathore
Abstract: Abstract This study evaluates the impact of varying proportions of recycled concrete aggregate (RCA) and steel fiber content on the compressive strength of concrete mixes. Five concrete mixes were prepared with different percentages of RCA (0%, 25%, 50%, 75%, and 100%), using a constant water-to-cement ratio (w/c) of 0.55. Additionally, each mix included variations with 1% and 2% steel fiber by volume, corresponding to 78.5 kg/m³ and 157 kg/m³, respectively. …
