Natural fibers are one of the most appropriate alternatives for designation and production of structural panels due to low final production cost. However a principal point is the strength loss caused by usage of these fibers in the matrix of cement based composites. Hence, a simple and cheap method should be applied to develop the properties of these fibers. Therefore, in this study by application of sulfite waste (along with waste management in the wood and paper industries) and usage of low-dosage silica nanoparticles (in order to enhance the interfacial transition zone of the cement-fiber paste), production of cement based sheets reinforced with natural fibers and silica nano-particles are investigated. Alongside, flexural strength and microstructure of sheets are examined by calculating the Modulus of Rupture (MOR) and Modulus of Elasticity (MOE), and applying the Scanning Electron Microscopy (SEM), respectively. Results show that mechanical performance and microstructure of cement based composites containing waste natural fibers and silica nano-particles can be improved.
