Experimental Study on Compressive Strength of M30 Grade Concrete Using Waste Glass Powder in Comparison with Conventional Concrete

Abstract

The aim of this study is to compare glass powder based M30 concrete to conventional concrete in terms of compressive strength. 18 samples were divided into two groups and prepped for data collection. The first is made using glass powder in place of fine aggregate, and the second is regular concrete. The preparation and examination of the samples involved using a variety of tools and materials. The pretest power is determined with 80% confidence intervals (CI) are 95% respectively. The 20% of glass powder was partially replaced in fine aggregate. Utilizing the universal testing machine, compression strength tests were conducted. The independent sample t-test was carried out using SPSS (Statistical Package for the Social Sciences) software, version 21. The mean compressive strength of concrete with innovative glass powder was 35.4978 N/mm 2 , whereas the typical mean compressive strength of conventional concrete is 34.2744 N/mm 2 . A t-test for independent samples is used to analyze the findings. The significance was p = 0.000 (p < 0.05). This demonstrates that the two approaches have a statistically significant difference. The standard deviation is 1.6697, 2.1529, and the standard error is 0.3935, 0.5074, with the mean value being 34.2744 N/mm 2 , 35.4978N/ mm 2 . From this experimental study, the innovative glass powder based M30 grade concrete is found to have a higher compressive strength than regular concrete, it is determined.
