 Abstract

In this study, the effect of waste glass powder on the properties of different grade concrete was examined by conducting a series of compressive strength, splitting tensile strength and flexural strength tests. According to this aim, waste glass powder (WGP) was first used as a partial replacement for cement and six different ratios of WGP were utilized in concrete production: 0%, 10%,15%, 20%, 25% & 30%.To examine the combined effect of different ratios of WGP on concrete performance, mixed samples were then prepared by replacing cement. For the hardened concrete, 150 mm C 150 mm C 150 mm cubic specimens and cylindrical specimens with a diameter of 100 mm and a height of 300 mm were tested to identify the compressive strength and splitting tensile strength of the concrete produced with waste glass powder. Next, a three-point bending test was carried out on samples with dimensions of 150 C 150 C 700 mm to obtain the flexure behavior of different mixtures. According to the test results, it is observed that the compressive strength of M30 grade concrete increases up to 25% replacement of waste glass powder after that strength is reduced. Flexural strength and Split tensile strength of M30 grade concrete gradually increases up to 20% replacement of waste glass powder and for 25% and 30% replacements the strength values are reduces .The compressive strength of M40 grade concrete increases up to 30% replacement of waste glass powder .Flexural strength and Split tensile strength of M40 grade concrete gradually increases up to 25% replacement of waste glass powder and for 30% replacements the strength values are reduces.
