Abstract
Development of concrete using alternative materials has become very important in the quest to achieve sustainable development in the built environment. However, it is critical to continually modify concrete mixtures to correct deficiencies of fresh and long-term properties. In this study, natural rubber latex and bamboo fiber were added as constituent materials in concrete, and the effects of the constituents on concrete were explored. Bamboo fiber (BF) and natural rubber latex (NRL) were added in proportions of 0%, 1%, and 1.5%. The study determined the workability (slump) of fresh concrete mixes, strength, and water absorption properties of the hardened samples after curing them in water for 7, 14, and 28 days. The morphology of the concrete samples was explored using SEM-EDX equipment. The results showed that samples having 1% bamboo fiber content and 1% rubber latex had the highest compressive strength among all the presented samples. Furthermore, samples containing equal but lower percentages of both bamboo and NRL had the highest compressive strength comparable to that of the control. This research showed the feasibility of combining bamboo fiber and rubber latex for an alternative eco-friendly construction approach to enhance the performance of conventional concrete in terms of tensile strength and flexural strength properties.
