Mechanical Properties of Some Agricultural Waste Self-Compacting Concrete

Purpose: This research aims to comprehensively investigate the effects of incorporating agricultural waste-derived supplementary cementitious materials (SCMs) on the properties of self-compacting concrete (SCC). Design/Methodology/Approach: Literatures published between 2010 and 2024 from a comprehensive search across reputable databases such as Scopus, ScienceDirect, Google Scholar, Elsevier, Springer, Taylor & Francis, MDPI and IEEE Xplore were sourced that studied and experimented on some of these agricultural wastes such as rice husk ash, sugarcane bagasse ash, corn cob ash, egg shell ash, palm kernel shell and walnut shell that were substituted as part of the cement in SCC mixes were reviewed and their results and findings studied closely. The data gathered from this literature were the results gotten from experiments and the effects of these agricultural wastes on the mechanical properties of self-compacting concrete. Research Limitation: The results from this literature may not be entirely reliable regarding long-term performance. Findings: This study demonstrates the potential of agricultural waste as a valuable resource for producing sustainable, durable, and high-performance SCC. Palm Oil Fuel Ash, Lytag, and Waste Tire Steel Fibres were studied in an experiment reported in the literature, where noticeable improvements were observed in compressive strength (+14.09%) and modulus of elasticity (+33.54%). Practical Implication: The negative environmental impact of greenhouse gas emissions from concrete production is drastically reduced by utilising agricultural waste SCMs, thereby limiting the amount of cement needed in production. Social Implications: Agricultural waste SCMs improved the mechanical properties of Self-Compacting Concrete, including tensile, compressive, and flexural strengths. The analysis showed increased resistance to degradation and durability. Originality / Value: This study contributes to reducing greenhouse gas emissions by partially replacing cement with agricultural waste in self-compacting concrete. It offers a comprehensive interpretation that combines durability, strength, environmental impact and usefulness.
