A Practical Study on Concrete by Partial Restitute of Cement by Orange Peel Ash in Additive with Polypropylene Fibers on M40 Mark

Abstract: Researchers have been looking at several materials to make concrete more sustainable in the past few years. The nutritional and therapeutic benefits of orange fruits have kept them in human diets for centuries. However, improper disposal of the orange peel wastes produced by fruit eating poses risks to both human and environmental health. The study's overarching goal was to develop environmentally friendly engineering material additions for use in concrete, with a secondary objective of reducing trash pollution and littering. With a focus on the strength properties of OPA-cement blends for cement replacement ranging from 0-10% at 2.5% intervals, this investigation will examines the potential of orange peel ash (OPA) as a cement replacement material. The effect of varied % additions of OPA on the qualities of fresh concrete was investigated experimentally by measuring consistency, fineness of cement, soundness of cement, setting times, workability, compressive, split tensile strength and flexural strengths. An ideal concentration of 0%, 2.5%, 5%, 7.5%, and 10% of OPA admixture was determined, and consistency improved with increasing additions on M40 Grade of Concrete.
