This study aimed to explore the possibility of utilizing crushed glass as an alternative fine aggregate for concrete by replacing concrete with crushed glass. Specifically, the study sought to assess whether there is a significant correlation between crushed glass volume in concrete and its compressive strength and also between sand volume in concrete and its compressive strength. Further, the study also determined whether there is a significant difference in the compressive strength between the concrete with crushed glass and that with sand as fine aggregates.
Experimental design was employed and this involved two sets of five mix proportions with three samples for each proportion. One set used sand and the other used crushed glass as fine aggregate. These samples were brought to the Qualitest Solutions and Technologies, Inc. (QSTI) for testing of compressive strength.
Finding showed that as the crushed glass volume in concrete increases, its compressive strength decreases and as the sand volume in concrete increases, its compressive strength decreases. Further, the compressive strength of concrete with crushed glass as fine aggregate is comparable to the compressive strength of concrete with sand as fine aggregate.
