Fibres from different parts of empty fruit bunch, which is a major solid waste oil palm processing, were subjected to pretreatments and characterised for variability in length diameter, mechanical performance, proximate trace element composition. Morphology surface composition the fibres determined using scanning electron microscopy with energy dispersive X-ray. The further treated KOH-boric acid characterized by Fourier transform infrared spectroscopy, X-ray diffraction, microscopy. Fibre...
The production of cellulose in the nano-scale size and their application as a reinforcement construction materials have gained increasing attention due to unique properties, such high tensile strength modulus elasticity, large specific surface area. This study aimed evaluate mechanical, physical thermal behaviour extruded earth-based matrix reinforced with 0.1%, 0.3%, 0.5%wt. nanofibrillated (NFC). results shown that mechanical nanofibrillation process fibre improves its stability. Their...
Hornification is an irreversible effect that occurs on lignocellulosic fibers when they are subjected to drying and re-wetting cycles. This study aimed evaluate okra raffia morphological, physico-chemical, mechanical properties. The were four six wet-dry treatment cycles assess the of number performance each fiber. results show increase in density from 1.40 g/cm3 1.78 1.34 1.58 for fibers, respectively. Furthermore, a decrease fiber lumen observed, resulting reduction water absorption...
The use of natural fibers to enhance the thermal properties earth bricks has become increasingly popular. This study investigates performance termite mold soil (TMS) reinforced with two types fibers: coconut (CF) and empty fruit bunch spikelet (EFBSF). Various fiber compositions (0%, 0.5%, 1%, 1.5%, 2%, 2.5%) were combined sodium hydroxide (NaOH) treatments at concentrations 3%, 4%. Laboratory results reveal that TMS exhibits promising physical properties, including a moisture content...
The non-biodegradability of plastics released into the environment makes soils infertile, impedes drainage waste water and rain in existing gutters spread waterborne diseases which are traits to human life. This study aimed at producing roofing sheet from polyethylene terephthalate (PET) river sand. Sand was collected while plastic bottles were environment. physical properties sand such as natural content, specific gravity, apparent density, grain size analysis, equivalent test Organic...
Agricultural and Industrial wastes have created waste management pollution problems. The replacement of conventional ingredients in concrete production would reduce construction cost proper management. percentages spikelet fibers the composites were 0%, 0.25%, 0.5%, 0.75% 1%. Concrete cubes rectangular bricks sizes 150mm x 40mm 160mm respectively with different cured tested after 7 28 days. flexural strength, compressive Density, slump workability, rate water absorption grain size analyzed....
The harsh tropical climatic conditions and rapid deterioration of building strictly from soil have rendered one billion people in developing countries homeless. To alleviate this situation the effect Palm oil mesocarp fibres was investigated on thermal properties cement-stabilized earth brick. Fibres were extracted pretreated with warm distilled water at 100 °C diluted 2% NaOH oven dry 105 for 24 hours. Sedimentary test, grain size, elementary Analysis conducted resulting clayey which has a...
One of the major factors influencing variation friction between surfaces in contact is speed; we are faced here with problem determining optimum speed order to improve on mechanical properties and performance entire system. This project investigates experimentally effect rotational (CoF) aluminum disk test samples stainless steel pin using plum oil as a lubricant under thin film lubrication conditions. We first extracted manual pressing method then carried out tests pin-on-disk tribometer...
