An Overview on Physical and Mechanical Properties of Bamboo as a Natural Reinforcement in Concrete
IOP conference series(2022)
摘要
Abstract Bamboo regained popularity as a reinforcement for concrete, especially in simple construction because of its high in tensile strength. Bamboo’s material that has a fast reproduction which increases its suitability to use as a sustainable source especially in construction works. However, when bio-based materials in general, and bamboo in particular, are expected to be used in construction, the sensitivity to moisture and their durability are usually questionable. Physical and mechanical properties bamboo should be improved by treated with chemical to prevent the bamboo from insects, pesticides and ensure the longevity of bamboo. Bamboo fibres are mainly used as a natural reinforcement in concrete that can minimize energy consumption, protect non-renewable natural resources, reduce pollution and maintain a healthy environment. Therefore, this study was to review and collect data for physical and mechanical properties of concrete containing bamboo as a natural reinforcement. The addition percentages of bamboo fibres 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, used in the research were evaluated. Overall, the bamboo fibres as reinforced concrete for 1.0% to 1.5% are the best ratio of mix designation that have significant increase in compressive and tensile strength that tested and reviewed after 28 days of curing. Meanwhile, the density test for concrete is shown lower compared to the British Standard of steel as reinforced in concrete. The treated bamboo that used chemical treatment were improved the bonding strength and reduced water absorption more than 50% compared to the untreated bamboo. Form the review that have been done, bamboo as reinforces in concrete are suitable for lightweight construction building.
