The global demand for structures is increasing, driving a need for construction materials. To meet this demand sustainably, manufacturers are seeking alternative resources. Scientists and engineers are leading the way, exploring innovative solutions to preserve natural resources while meeting infrastructure needs. In this study, the focus is on exploring the effect and benefits of using pulverized waste glass bottles as a partial replacement for fine aggregates in concrete hollow blocks. The aim is to understand how incorporating waste glass affects the properties of CHBs, particularly in terms of workability, compressive strength, and overall performance. The study explores the feasibility of integrating pulverized waste glass bottles into concrete hollow blocks, aiming to assess its impact on workability and compressive strength. Through rigorous testing methodologies, including One-way Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT), the study evaluates the performance of concrete with varying percentages of waste glass bottle replacements across different curing periods. Results reveal that despite the substitution of fine aggregates with waste glass bottles, concrete maintains satisfactory workability, crucial for efficient construction practices. Notably, Treatment 4 (T4), featuring a 9% waste glass bottle replacement, demonstrates superior compressive strength compared to other treatments at the 14th day curing period. Furthermore, Treatment 2 with 3% pulverized waste glass bottles exhibits advantages over Treatment I (control) at later curing periods. A cost-benefit analysis suggests potential savings and environmental benefits associated with waste glass bottle integration, while optimal replacement percentages are identified to ensure structural integrity. The study's recommendations include further research on mechanical properties, government initiatives for recycling programs, and academic investigations into long-term performance. Overall, the findings underscore the potential of waste glass bottle incorporation in concrete production for sustainable construction practices.
