This study begins by introducing the basic components of concrete and addressing environmental concerns associated with its production, particularly the depletion of natural aggregates and the challenges of construction waste disposal. As potential solutions recycled aggregate concrete (RAC) and fiber-reinforced concrete (FRC) are explored for their ability to enhance sustainability. A comprehensive review of existing literature follows, covering natural fibers, their treatment methods, recycled coarse aggregates, and the potential benefits of combining these materials in concrete. The study then defines its objectives and scope, focusing on evaluating the effects of natural fibers and recycled aggregates on the compressive strength, workability, and density of concrete, while also assessing their role in promoting environmental sustainability.
The research methodology includes a detailed explanation of the materials used, concrete mix proportions, and the sourcing and treatment of corn straw fibers. The process of mixing concrete with these fibers, compaction, curing, and the various tests conducted—such as compressive strength tests, rebound hammer tests, flexural strength tests, water absorption tests, and sulphate attack tests—are outlined. Experimental work involves the mix design for M25 grade concrete, preliminary testing, and the casting and testing of concrete cubes and beams. Finally, the study presents the experimental results, including compressive strength trends, rebound hammer test findings, 7-day and 28-day strength measurements, water absorption data, flexural strength results, and sulphate attack test outcomes, offering insights into the performance of fiber-reinforced recycled aggregate concrete.
