Abstract/Executive Summary

The construction industry is a major consumer of natural resources, with sand extraction contributing to environmental degradation. At the same time, glass waste continues to accumulate due to weak recycling systems. This study investigates the use of pulverized clear waste liquor glass bottles (PWGB) as a partial to full sand replacement for sand in the production of concrete hollow blocks (CHBs). The objective was to determine whether PWGB can serve as a sustainable substitute for natural sand by evaluating its effects on net compressive strength, water absorption, dry density, and moisture content. A quasi-experimental design was employed, with CHBs produced at replacement levels of 15%, 25%, 50%, 75%, 100%, alongside commercial CHBs as controls. The blocks were molded, cured for 14 days, and tested under standardized procedures. Results revealed that CHBs with higher substitution levels (75% and 100%) demonstrated competitive compressive strength and acceptable physical properties compared to commercial CHBs. Water absorption and density values varied across replacement levels but remained within practical ranges. The findings suggest that PWGB can be effectively utilized as a sustainable alternative to sand in CHB production, addressing both sand scarcity and glass waste accumulation. This study concludes that integrating recycled glass into construction materials supports environmental sustainability and offers potential economic benefits for local communities and industries.
