Globally, as human population and industries grow, so does the creation of agricultural, industrial, and demolition waste. When these wastes are not properly recycled, reused, or disposed of, they pose a threat to the environment. The importance of this study lies in the beneficial use of coconut fibre and mineral wool in the form of fibres in cement mortar production. This study examines the use of coconut and mineral wool fibres in the production of fibre-reinforced mortar. Five different mortar mixtures were prepared, having one control mortar along with four fibre-reinforced mortars. The control mortar is denoted as CM while 1% and 1.5% of mineral wool are incorporated into this mortar mix and denoted as RMM-1.0 and RMM-1.5, respectively. Additionally, the mortar sample configurations contain 1% and 1.5% coconut fibers, designated as RCM-1.0 and RCM-1.5. These samples were subjected to different strength and durability tests to determine their suitability for use in mortar production. The testing findings show that mortar containing 1.5% mineral wool has better compared flexural strength and durability properties. The investigation results will form part of the database for the efficient utilization of natural and waste fibres in the construction and building sectors.
在全球范围内,随着人口和工业的增长,农业、工业和拆除废物的产生量也在增加。当这些废物没有得到妥善回收、再利用或处理时,就会对环境构成威胁。本研究的重要性在于以纤维形式将椰壳纤维和矿棉用于水泥砂浆生产的有益用途。本研究考察了椰壳纤维和矿棉纤维在纤维增强砂浆生产中的应用。制备了五种不同的砂浆混合物,其中一种为对照砂浆,另外四种为纤维增强砂浆。对照砂浆记为CM,在该砂浆混合物中分别掺入1%和1.5%的矿棉,分别记为RMM-1.0和RMM-1.5。此外,砂浆样品配置中含有1%和1.5%的椰壳纤维,分别指定为RCM-1.0和RCM-1.5。对这些样品进行了不同的强度和耐久性测试,以确定它们在砂浆生产中的适用性。测试结果表明,含有1.5%矿棉的砂浆具有较好的抗弯强度和耐久性。研究结果将成为建筑和建筑行业有效利用天然和废纤维数据库的一部分。
