“…The plain concrete was discovered to develop 20 -30% compressive strength increment than that of concrete with CSA (Coconut Shell Ash) as reported by [43]. 25% of coconut shell fiber was used for partial replacement of certain percentages of concrete aggregates.…”

Wastes generation and emission of greenhouse gases are the major concerns of the contemporary world. Concrete’s cements companies in the globe are producing up to 2.8 billion tons of cements annually. This contributed to the emission of anthropogenic substances into the atmosphere which destroys the ozone layers. The incessant disposal of these agricultural wastes has detrimental effect on the environmental and human health. Thus, utilizing these wastes as secondary resources in concrete is a reasonable consideration in sustainable waste management in the circular economy. The use of agricultural wastes in concrete production has been gaining attraction in recent years, however, their effectiveness and performance in concrete need evaluation. This study presents an overview of the effects of some agricultural wastes: Bagasse, Coconut shell, Cotton, Oil palm and Hemp fibers on concrete and composite’s mechanical properties. As reviewed, Sugar-Cane Bagasse Ash (SCBA) and Coconut Shell Ash (CSA) are rich in cementitious (pozzolanic) properties (SiO2, Fe2O3 and Al2O3) for cement production up to 70%. Sugar-cane bagasse and oil palm-fiber ashes improved concrete workability. SCBA and CSA highly increased the concrete compressive strengths. The concrete tensile strengths were increased up to 97% with the inclusion of cotton and bagasse ashes. The SCBA, hemp-fiber and treated oil palm - fiber ash increased the concrete and composite’s flexural strengths up to 11.3%, 26.2% and 50.7% respectively. In conclusion, the output of this review will supply full data of the research gaps yet to cover on the use of agro-wastes in concrete for future investigations

“…According to the authors, coconut shell ash is not good for concrete reinforcement, especially, to improve its flexural strength. In addition to the above statements, according to [43], the higher the proportion of CSA in concrete, the more the decrease in its flexural strength.…”

Agricultural waste based roofing materials can be useful in the construction of farm structures and green buildings. This study evaluated the transverse breaking strength, flexural strength and Water Absorption properties of concrete roofing tile replacing the conventionally used sisal fiber which provides transverse strength with coir fiber and plaster sand with clay soil. Five roofing tile samples of different mix design were produced. The result attained for the flexural test and transverse breaking strength for all roofing tile samples at 28 days test showed that roofing tile replace with 100% coir fiber can also be used commercially although it is not as strong as the roofing tile with 100% coir fiber. The result attained for water absorption was within the acceptable value according to ASTM C1492.
