Abstract
Material shortages throughout the supply chain have become a serious problem. Effective material management is vital to solve shortages and limit inventory costs. The continued demand for building services leads to increasing costs. Sustainable building materials serve a crucial role in resolving environmental issues and boosting resilience in civil engineering projects. The easiest technique to handle this problem is includes the waste products towards elements in concrete. As we know that so many wastes which can be used in traditional concrete like E- wastes, biomedical wastes, Agricultural wastes etc. Coconut casing and orange peel ash are also the key waste which is easily and plenty available in home needs and that can be used in usual concrete. Coconut shell material could be used in rural areas and places where coconut is plentiful and may also be used where the usual aggregate is costly. With a focus on the strength properties of OPA-cement blends for cement replacement ranging from 0-12% at 2% 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%, 4%, 6%, 8%, 10% & 12% of OPA admixture was determined, and consistency improved with increasing additions on M30 Grade of Concrete. The Coconut Shells(CS) were taken on constant 5% with replacement of coarse aggregate and Orange Peel Ash(OPA) were taken on 0%, 2%, 4%, 6%, 8%, 10% & 12% with limited replacement of cement on M30 Grade of Concrete(GC).This study continues to seek creative methods to employ such materials in sustainable building processes.Key Words: Coconut Shell (CS), Orange Peel Ash (OPA), Cement & M30 GC.
