Experimental Investigation On Lightweight Concrete Containing Oil Palm Kernel Shell As Replacement Of Coarse Aggregate And Binding Material With Flyash

Abstract

Sanctuary is a basic human need. Alas, adequate shelter for the majority; the destitute has remained elusive over time. The expense of concrete materials in construction and civil engineering projects has been a source of worry for the public. As a result of these and other factors, study has been conducted on genetic local resources that are thrown as trash into our environment, creating contamination and traffic clogging as alternative materials. As a result, this study was conducted in order to gauge the usage of palm kernel shell as a partial substitute for coarse aggregate in concrete. Oil palm kernel shell (OPKS) is a bio solid waste from the palm oil industry in tropical regions that may be utilised as a concrete aggregate. Since 1984, OPKS has been used in research projects to make lightweight concrete as a natural lightweight aggregate (LWC). The fresh, mechanical, and bond characteristics of grade M30 lightweight concrete, specifically oil palm kernel shell concrete (OPKSC), are compared to similar strength normal weight concrete (NWC). The OPKSC has utilised oil palm kernel shell (OPKS), an industrial waste, into lightweight aggregates (LWA). A constant 5 percent flyash was used as a preferential replacement of binding material for every combination of mix proportions of 10 percentage, 20 percentage, 30 percentage, and 40 percentage oil palm kernel shell partial substitute of course aggregate. When compared to NWC, the OPKSC produced a density drop of around 20%.
