In present, environmental pollution is become serious problem. Agricultural products generate waste in huge amount, which creates the disposal and environmental problems such as leachate and odour smell. An initiative is needed to reduce these wastes and utilize the agricultural waste as a construction material like concrete. The agricultural waste widely used as supplementary cementing material, filler and fibre reinforcement. In this research Banana Skin Powder (BSP) and Coir Fibre (CF) utilized as partially cementing material and filler respectively, to reduce the agricultural waste and save the natural recourses which is used in manufacturing of cement and reduces the emission of carbon dioxide (CO2) in atmosphere. This research investigated the physical and chemical properties of BSP. The fresh properties (filling ability, passing ability and segregation resistance) and hardened properties such as compressive, tensile, flexural strength, modulus of elasticity and Poisson’s ratio of self-compacting concrete (SCC) consisting BSP and CF were studied experimentally. The ultimate load, crack pattern and load deflection profile of Precast Self-Compacting Concrete containing BSP and CF Beam (PSCC-BSP-CF-B) were analysed under flexural load by experimental work. The results were validated by Finite Element Analysis (FEA) using software package Abaqus. The outcomes from XRF test proved that the BSP is the Class F pozzolan which contributes to enhance the strength of SCC. The fresh properties of SCC like filling ability, passing ability and segregation resistance were satisfied the EFNARC SCC specifications. The mechanical properties and ultimate bearing capacity were improved with the BSP and CF incorporation in SCC. The crack pattern predicts the PSCC-B were fail in flexural. The deflection became lower when CF and BSP were added in PSCC-B. The optimum percentage which was found through experimental tests are 0.4%BSP and 0.5% for CF. The crack pattern, ultimate load and deflection in PSCC-B using FEA through ABAQUS have 2% to 8% difference compare to experimental studies.
