Some of the physical and mechanical properties of cement composites manufactured from carbon nanotubes and bagasse fiber

Effect of carbon nanotube on physical and mechanical properties of natural fiber/glass fiber/cement composites

“…Also, MWCNTs are naturally waterproof which causes an increase in water resistance properties of the manufactured composites. Younesi Kordkheili et al (2012) reported that increasing MWCNTs from 0.5 to 1.5 % reduced water absorption and thickness swelling in bagasse fiber-cement composites.…”

“…Compared to glass fibers, bagasse fibers, which are natural fibers, have lower density and cost and are renewable and biodegradable. These composites also have low thermal conductivity, reduce environmental pollution by recycling bagasse fiber, and do not emit formaldehyde as do typical composite panels (such as MDF and Particle board) during their service life (Younesi Kordkheili et al 2012). Previous research showed that the main disadvantage of cement type panels made from bagasse fiber was vulnerability to moisture and reduced mechanical properties as compared to panels made with polypropylene fiber or glass fiber (Pehanich et al 2004;Aggarwal 1995).…”

“…Hybrid composites manufactured from two reinforcing agents (natural and synthetic fiber) had desirable properties such as being lightweight, easy to construct, economical, demountable, recyclable and reusable (Abeysinghe et al 2013). Use of nano-materials (such as carbon nanotubes or nanoclay) to produce nanocomposites is another suggested method to overcome the negative effects of cementitious composites (Younesi Kordkheili et al 2012).…”

Theoretical and experimental analysis of multifunctional high performance cement mortar matrices reinforced with varying lengths of carbon fibers

“…1800 kg/m 3 (as per manufacturer product data sheet) and 'm' is the mass of carbon fiber. The number of carbon fibers 'N' enclosed in a cubic millimeter of carbon fiber filled cement based composite can be estimated by the following expression [5]:…”

“…Fiber reinforced cementitious composites (FRCCs) are gaining importance for their superior mechanical, electrical and chemical properties. Although the history of fibers utilization in composites dates back to 1500 BC but in recent years many new types of synthetic fibers have been developed and being utilized along with natural fibers such as polypropylene (PP), polyvinyl alcohol (PVA), steel, glass, carbon fibers (CFs) and carbon nanotubes (CNTs) (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Among synthetic fibers, CFs possess exceptional physical and mechanical characteristics; therefore, they are being used as reinforcement to augment the mechanical properties (i.e.…”
