Geopolymers Reinforced with Natural Fibers: A Comparison among Different Sources
نویسندگان
چکیده
The performance of different natural fibers (hemp, kenaf and bamboo) used to formulate composites with an alkali-activated matrix based on metakaolin is evaluated. Short were randomly dispersed up about 3% the binder weight, fresh cured properties derived determined. Up investigated fraction, it still possible obtain adequate workability without supply additional water or additives. Upon modification fibers, mechanical behavior changes from completely brittle pseudoplastic increased toughness. flexural strength increases by 80% at highest bamboo amount 20% for kenaf. Hemp have a negligible effect but strongly improve materials’ Moreover, addition does not change manner in which material interacts moisture. Indeed, uptake modified samples was comparable that unmodified samples, showed decreased rate diffusion as fiber increased.

متن کاملComparison of denture base resin reinforced with polyaromatic polyamide fibers of different orientations.
The aim of this study was to evaluate the effect of reinforcing polyaromatic polyamide (aramid) fibers with various orientations on the flexural properties of denture base resin. Aramid fibers with four orientations of unidirectional, woven, non-woven and paper-type were pre-impregnated and placed at the bottom of a specimen mold. Heat-polymerized denture base resin was packed over the fibers a...
متن کاملDevelopment and Characterization of Polymer Eco-Composites Based on Natural Rubber Reinforced with Natural Fibers
Natural rubber composites filled with short natural fibers (flax and sawdust) were prepared by blending procedure and the elastomer cross-linking was carried out using benzoyl peroxide. The microbial degradation of composites was carried out by incubating with Aspergillus niger recognized for the ability to grow and degrade a broad range of substrates. The extent of biodegradation was evaluated...
متن کاملImprovement of Strength Parameters of Sand Reinforced with Polymeric Fibers
Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
