“…Bamboo fits into this category due to its considerable tensile strength and renewable nature. Bamboo has become a reliable replacement for steel in structural elements [11]. Previous studies by Premkumar & Vasugi [12] and Qaiser et al [8] have identified bamboo to be suitable for rural construction where steel reinforcement is not affordable.…”

The growing concern to reduce global warming has necessitated the use of more eco-friendly materials in construction. The study is focused on the utilization of cassava peel ash as supplementary cementitious material and bamboo as reinforcement in concrete beams. The response surface methodology approach was explored to determine the effect of simultaneously varying the cassava peel ash content, bamboo size, beam length, and beam depth on the flexural strength and strain of beams. An analysis of variance was carried out on experimentally obtained results to determine the accuracy of the obtained models and the contributions made by the linear interaction and quadratic terms on flexural strength and flexural strain. The coefficient of determination obtained for RSM models showed a good correlation between all predicted and experimentally obtained results. The optimum conditions obtained for bamboo-reinforced concrete containing cassava peel ash were 3% cassava peel ash, 16 mm bamboo diameter, 500 mm beam length, and 150 mm beam depth. The predicted flexural strengths were 11.85, 14.34, and 14.95 N/mm2 and flexural strains of 0.64, 0.67, and 0.91 for 28 days, 56 days, and 90 days, respectively. To validate the model prediction, a laboratory experiment was conducted using the optimum mix design proportion. From the results obtained, it was observed that the experimental results were close to those predicted by the models. These models can be efficiently used for simulating the flexural behavior of bamboo-reinforced concrete beams. Doi: 10.28991/CEJ-2023-09-08-011 Full Text: PDF

“…The ever‐increasing urbanization that mainly emanates from rapid population growth, particularly in developing countries, has placed much pressure on the demand for building materials in the construction sector. Hence, to maintain a sustainable construction industry, several innovative studies have investigated the relative performance of alternative design methods and materials to conventional ideologies 1‐4 . Javadian et al noted that the contribution from developing countries to the overall demand on concrete as a building material is approximately 90%.…”

“…A suitable option will be to use bamboo as longitudinal reinforcement for concrete structures that are not subjected to severe loading conditions. Extensive researches 3,4,7‐10 on the mechanical behavior of bamboo have revealed that it possesses a comparable tensile strength in relation to mild steel and, as such, can serve as a suitable replacement for steel. However, reliable quantification of its tensile strength is problematic as it is naturally occurring, therefore giving bamboo a wide variability in strength.…”

“…However, reliable quantification of its tensile strength is problematic as it is naturally occurring, therefore giving bamboo a wide variability in strength. Therefore, studies on its performance have mainly aimed at finding the optimum percentage of reinforcement that gives a maximum level of ductility under loading. Khare recommended that an optimum of 4% longitudinal reinforcement should be utilized in the design of bamboo‐reinforced concrete structure, in order to maintain an appreciable ductile behavior before ultimate failure.…”

“…Some researchers have also noted that bamboo construction may be suitable for rural construction where sophisticated equipment may not be available. Therefore, the more recent innovative concrete technology—self‐compacting concrete (SCC), which is gradually gaining wide usage—may be applicable for use when bamboo is employed as the reinforcing material.…”

The use of bamboo as longitudinal reinforcement, coupled with the application of self-compacted concrete (SCC) in the construction industry, may be a promising solution to issues involving sustainable development in developing countries. This study seeks to investigate the flexural performance of bamboo-reinforced SCC beams with adequate transverse reinforcement. The major design parameters were the shear span-to-depth ratio, the percentage of longitudinal reinforcement, and the maximum size of coarse aggregate. The load-deflection curves, serviceability and ultimate failure characteristics, cracking behavior, and ductility measures were evaluated and discussed among tested beams. Results indicated that their structural performance at service and ultimate failure would be adequate when a material reduction factor of three is used with BS 8110 design code. However, to achieve maximum ductility, the level of longitudinal reinforcement should be in range of 2.6-3.1%. Furthermore, an increase in the size of coarse aggregate will greatly impact the degree of ductility.

Hence, to maintain a sustainable construction industry, several innovative studies have investigated the relative performance of alternative design methods and materials to conventional ideologies. [1][2][3][4] Javadian et al 5 noted that the contribution from developing countries to the overall demand on concrete as a building material is approximately 90%. Additionally, Hebel et al 6 established that developing countries also account for about 80% of the global demand of steel in the construction industry. However, most of such countries are unable to synthesize these materials, particularly cement and steel, and rely heavily on importation from others. Hence, alternative building materials, which are readily available, affordable, and able to exhibit adequate structural behavior under all forms of external loading, are greatly preferred.A suitable option will be to use bamboo as longitudinal reinforcement for concrete structures that are not subjected to severe loading conditions. Extensive researches 3,4,7-10 on the mechanical behavior of bamboo have revealed that it possesses a comparable tensile strength in relation to mild steel and, as such, can serve as a suitable replacement for steel. However, reliable quantification of its tensile strength is problematic as it is naturally occurring, therefore giving bamboo a wide variability in strength. Therefore, studies 3,4,11,12 on its performance have mainly aimed at finding the optimum percentage of reinforcement that gives a maximum level of ductility under loading.
