Abstract:
In today’s age, finding harmony between construction endeavors and safeguarding the environment is of utmost
importance. Consequently, there is a substantial requirement to explore the feasibility of utilizing waste materials as a replacement for traditional construction substances. Unfortunately, there is a lack of information
regarding the possibilities of incorporating recycled glass, rice husk, and sugarcane bagasse ash into concrete
production. This study investigated the viability of integrating recycled glass fibres and agricultural waste ash
into concrete to bolster its strength and sustainability. When evaluating mechanical and durability properties
across five mixtures, the concrete formulations ranged in fibre content percentages from 1% to 3% and in ash
content percentages from 10% to 20%. Specifically, Mixtures 1, 2, 3, 4, and 5 contained 1% fibre and 10% ash,
2% fibre and 15% ash, 2.5% fibre and 20% ash, 3% fibre and 12% ash, and 1.5% fibre and 18% ash respectively.
Mixture 2 and Mixture 5, boasting heightened fibre and ash content, showcased outstanding compressive
strength at 38.5 MPa and 37.2 MPa, respectively, indicating a positive correlation between these materials and
concrete strength. Conversely, Mixture 3, burdened with excessive fibre and ash content, witnessed diminished
strength, underscoring the necessity for meticulous optimization. In terms of tensile and flexural strength,
Mixture 2 and Mixture 5 displayed commendable performance, while Mixture 3 suffered setbacks from excessive
content. Durability assessments unveiled Mixture 1 and Mixture 4’s superior freeze-thaw resistance, with minimal mass loss (1.5% and 1.8%, respectively) and no visible damage, rendering them favorable choices for
sustainable construction. Contrastingly, Mixture 3 exhibited poorer freeze-thaw resistance and higher environmental impact, highlighting the need for careful consideration in material selection. Overall, this study underscores the importance of optimizing concrete formulations through the integration of recycled materials,
paving the way for stronger, more durable, and environmentally friendly construction practices.
