Abstract

In recent years, the use of waste glass powder as a partial cement replacement has been researched widely to reduce the amount of waste glass from the environment. In this study, the potential use of waste glass powder, derived from soda lime silica bottles, as cement replacement was studied through microstructural and compressive strength analysis. Microstructural behaviour was studied using x-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). Compressive strength tests were carried out on cement mortar to investigate the strength properties. Glass powder used in this study was in the range of 150-75 µm. Cement was replaced by 10%, 20%, 30% and 40% glass powder. When cement was replaced by glass powder, the reduction in the Calcium Hydroxide (CH) content was observed along with production of additional Calcium Silicate Hydrate (C-S-H). Specimen with 10% replacement revealed highest compressive strength than other combinations. However, experimental results indicated that the compressive strength of mortar decreased as the percentage of waste glass powder increased in mixture.
