Effect of High Performance Concrete in PCC Structure by Partial Replacement of Agricultural Waste


Background/Objectives: The experimental investigations are carried out to study the effect of agricultural waste in PCC structure by partial replacement of cement and aggregate with wastes. The agricultural and industrial wastes used are Bagasse Ash, Fly ash and Coconut shell. Here the Bagasse ash and coconut shell has been physically characterized, and partially replaced by weight of cement and aggregate in concrete. Methods/Statistical Analysis: This study has been aimed to evaluate the strength of the concrete by performing standard tests like compressive strength, split tensile strength and flexural strength at the age of 3, 7 and 28 days and physical properties test were also conducted and compared. The bagasse ash and coconut shell have been replaced partially with the concrete of about optimum of 25% respectively. Instead of cement, bagasse ash is utilized with varying proportions and the strength values are evaluated and tabulated. Similarly coconut has been utilized with the conventional concrete for the replacement of coarse aggregate. Findings: The strength parameters are evaluated with the specimen of bagasse ash and coconut shell.In this study, bagasse ash has been partially replaced with the cement to determine the physical and chemical properties of the concrete and then it is compared with the conventional concrete. Similarly coconut shell has been replaced partially with the coarse aggregate for evaluating the strength parameters. In past research, the bagasse ash replacement was given the results of about 90% with 15% of replacement of cement with bagasse ash.In this present study, obtained the optimum strength of about 80% with the replacement of bagasse ash as of about 25%. The utilization of more than 25% of bagasse ash in concrete, strength is gradually reduced with the target strength of conventional concrete. Applications/Improvements: Further research in this study is to use the chemical admixture to improve the bonding strength,then the strength might have been increased with that of conventional concrete. The major application of this concrete is to use as a constructional material for the non structural elements like kitchen slab, man hole cover and compound walls.
