The Impact of Glass Powder on Concrete's Mechanical Properties: A Sustainable Approach

Abstract

This study investigates how concrete's mechanical qualities are affected when glass powder is used in part in place of cement. The effects of different glass powder percentages (0%, 3%, 6%, 9%, and 12%) on compressive strength, split tensile strength, and flexural strength over 7, 14, and 28-day curing times were examined. The findings show that adding up to 9% glass powder to concrete greatly increases its flexural, split tensile, and compressive strengths. Strength attributes were found to deteriorate beyond a replacement level of 9%, which was the maximum improvement. This study shows how glass powder can be used as a useful cement additive, supporting more environmentally friendly building methods.
