Description
Summary:This paper describes the reinforcement of composite brick based on kenaf cellulose nanofibrils (CNF). Kenaf bast was explored to produce CNF using high-intensity ultrasonication as an economical, time saving and environmental-friendly of isolation process. Raw kenaf fibres underwent an alkaline treatment to eliminate the non-cellulosic compounds before proceed to a high-intensity ultrasonication process. FESEM micrographs was used to confirm the presence of nanofibrils in kenaf CNF. Four different moulds were used to fabricate one brick without CNF (control brick) and three composite brick with different amount of CNF, sand, cement and stone. The mechanical strength of four fabricated bricks were determined for compression test using the Universal Testing Machine (UTM). The composite brick 3 has the highest mechanical strength due to highest value of Young’s Modulus which is 930.88 N/mm2. Kenaf CNF has superior toughness and was improved its mechanical properties after alkaline treatment.
