Item Effect of Date Seed Particulates on Mechanical Properties of Aluminium Alloy(Faculty of Engineering Hunedoara, University Politehnica Timisoara, 2018) Abdulkareem, Sulaiman; Edache, E. J.; Olowosule, I. I.; Kolawole, M. Y.; Ahmed, Ismaila Idowu; Ajiboye, Tajudeen KThe results of an experimental investigation of mechanical properties of date seed particles reinforced aluminium alloy composites, processed by stir casting method are reported in this paper. Two sets of composites with date seed of 300 and 500 µm particle sizes were used. The ranges of particle size used were based on the weight fraction when sieve analysis was conducted on the sample collected for the work. Each grain size had four types of composite samples with the reinforcement weight fractions of 5, 10, 15 and 20%. The mechanical properties considered were the tensile strength, Impact and hardness behaviors. Unreinforced aluminium alloy samples were also tested for the same properties. It was found that the hardness and tensile strength increases with the increase in the weight fraction and the fracture toughness decreases with increase in the weight fraction of reinforced date seeds particles. It was concluded that the improvement in the mechanical properties can be well accredited to the high dislocation density.Item Physical and Mechanical Characteristics of Charcoal, Sawdust and Sugarcane Bagasse as Solid Fuel Materials(Malaysian Technical University Network, 2017-12-19) Abdulkareem, Sulaiman; Badejo, H. A.; Ahmed, Ismaila Idowu; Adebisi, Jeleel Adekunle; Yahaya, Taiwo; Ajiboye, Tajudeen K; Abdulrahim, A. T.This paper reports on the physical and mechanical characteristics of briquettes produced from charcoal, sawdust and sugarcane bagasse using molasses with sodium silicate as binders. Charcoal, sawdust and sugarcane bagasse were mixed in a respective ratio of 20:20:60, 20:30:50, 20:40:40, 20:50:30 and 20:60:20. The briquettes were produced using Budenberg dial gauge compression machine, with a pressure of 64 MPa at 120 seconds dwell time. Physical properties (relaxation ratio, compaction ratio and shattering index) and mechanical property (compressive strength) of the produced briquettes were investigated. Results show that briquette with sample composition of 20:30:50 has better physical properties with a relaxation ratio of 1.562, a compaction ratio of 7.573 and shatter index of 99.6%, while sample with ratio 20:40:40 has the highest compressive strength of 55.43 kN/m2.
