Use of Pulverized Recycled Glass in Concrete

9 pagesPublished: May 15, 2022


The potential to use recycled products in building methods and materials is important to consider. A problem exists in the recycling process where many city municipalities have removed glass recycling from their recycled waste stream forcing consumers to waste glass into a common waste stream for all waste. At Central Washington University (CWU), use of pulverized glass in concrete was analyzed to determine the difference in strength of the concrete when reducing the amount of virgin concrete sand in concrete as a material. With an applied research methodology, the researcher studied the effects of reducing virgin sand and replacing it with locally sourced pulverized glass. A control was used for a typical 3,000 psi concrete mix commonly found in structural concrete applications on roads, bridges, buildings, and foundations. Reductions in virgin sand were made at 25% and 50% and replaced with pulverized glass at the same percentage within the concrete mixture. Concrete compression tests were performed on three concrete 6-inch by 12- inch cylinder samples at the specified virgin sand and sand reduction levels using the American Society of Testing Materials (ASTM) standards. Results showed an eleven percent (11%) and twelve percent (12%) reduction in concrete strength using pulverized glass for sand.
