This work investigates the reutilisation of natural (SCB) and modified sugarcane bagasse fibres with aminopropyltriethoxysilane (MSCB) in cementitious composites. The modified fibres were used in the treatment of effluents contaminated with oil-engine. A full factorial design was used to identify the effects of fibre type (natural and modified sugarcane), fibre length (0.6 and 1.2 mm), fibre amount (1 and 2wt%), and fibre condition (before and after oil filtration) on apparent density, water absorption, apparent porosity, ultra-pulse velocity, dynamic modulus, flexural strength and modulus. SCB fibres led to increased apparent density compared to MSCB fibre reinforced composites. The MSCB fibres contributed to reduce the porosity of the composite, leading to higher mechanical properties. The reduced area of MSCB fibres increased the amount of cementitious phase per unit volume which increases the sample strength. Longer fibres (1.2 mm) have a higher surface area, leading to a higher concentration of fibres per unit volume, increasing water absorption by 17%. The amounts of fibres had no significant effect on the mechanical and physical responses. Samples made with 2wt% MSCB fibres of 0.6 mm in length achieved promising results for non-structural applications in civil engineering.
This work investigates the reuse of natural (SCB) and aminopropyltriethoxysilane-modified (MSCB) sugarcane bagasse fibres in cementitious composites. Sugarcane bagasse fibres are pre-used in the treatment of motor oil contaminated effluents. A full factorial design is used to identify the effects of fibre type (SCB and MSCB), fibre length (0.6 and 1.2 mm), fibre amount (1 and 2 wt%) and fibre condition (before and after oil filtration) on apparent density, water absorption, apparent porosity, ultra-pulse velocity, dynamic modulus, flexural strength and modulus. SCB fibres lead to increased apparent density compared to MSCB fibre reinforced composites. MSCB fibres contribute to reduce composite porosity, leading to higher mechanical properties. The smaller area of MSCB fibres promotes a larger amount of cementitious phase per unit volume, thus increasing the strength of the sample. Longer sugarcane fibres (1.2 mm) have a larger surface area, leading to a higher fibre concentration per unit volume, which increases water absorption. The amount of fibre has no significant effect on mechanical and physical responses. Composites made with 2 wt% 0.6 mm long MSCB fibres achieve promising results for non-structural civil engineering applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
