This research examines the fresh properties, strength performance, and morphological analysis of self-compacting coconut shell concrete (SCCSC) blended with crushed coconut shell and manufactured sand (M-sand).Crushed coconut shell (CS) was used as a coarse aggregate (CA), and M-sand replaced river sand (R-sand) at 25%, 50%, 75%, and 100%.The study focused on the workability characteristics, mechanical behavior, and microstructural analysis of SCCSC.Experiments were performed on fresh and mechanical characteristics, including slump flow diameter, T500 slump flow time, L-Box blocking ratio, V-funnel and a wet sieving stability test.Mechanical Foods Pelleted characteristics include compressive, split tensile, flexural, impact resistance and bond strength.

Utilizing M-sand develops the mechanical performance of SCCSC.The morphological characteristics, using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) and the X-ray diffraction (XRD) technique, were studied in this research work.The findings show that the addition of M-sand increases the concrete strength.The microstructural analysis demonstrates that adding different amounts of M-sand to SCCSC reduced the porosity and anhydrous cement percentage, although it increased calcium hydroxide and hydration products.The substitution of 100% M-sand at Pain Patches 28 days increased compressive strength by 3.

79% relative to the reference SCCSC.Based on the findings, the mechanical strength of SCCSC containing M-sand significantly improved compared to the concrete with river sand.
