Abstract

Abstract: In this study, ground rice husks (GRH) in combination with polyvinyl-alcohol (PVA) fiber were used to produce low-cost and high-quality hybrid cementitious composites. Different amounts of GRH (2.5, 5.0, 7.5 and 12.5% in weight of cement) were added to the concrete. The work presented in this paper provides an insight into the use of an agricultural waste as effective additive in cement based materials. The properties of resultant cementitious composites including density, water absorption, flexural behavior and compressive strength were investigated. The results have shown that incorporation of ground rice husk in combination with PVA fiber can be effective in improvement of the flexural properties of cementitious composite. The study explored the effectiveness of this type of agricultural waste as a beneficial material in fine aggregate concrete materials. Highlights: Lightweight cementitious composite containing agricultural waste. High strength cementitious composites with strain-hardening behavior containing waste materials. Significant effect of rice husk as reinforcement in cement based materials. Combination of polymer fiber and agricultural waste in concrete materials.
