The effect of using different firing temperatures of waste glass for the production of glass bricks

Glass is a popular and common material used in our daily life because of their properties such as transparency, high compressive strength, chemical resistance and durability. Thus, large amounts of waste glass production are unavoidable. Hence, enhancing the recycling of these resources and using them wisely provide a significant challenge to industry and academia. The purpose of this study was to provide a method for recycling waste glass in the production of glass bricks. To achieve this goal, the complete process, encompassing the production of mould, the production of glass bricks and subsequent testing for glass bricks characterization. The waste glass was used in this research for the production of glass bricks. The firing temperature of the production glass bricks were 850 ℃, 950 ℃ and 8 hours exposure time. The properties of mould samples were investigated using X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA). The properties of waste glass were investigated using XRD and Fourier Transform Infrared (FTIR). The properties of glass bricks after being fired at 850 ℃ and 950 ℃ were investigated using density and porosity test, compression test, and FTIR. The 950 ℃ of glass bricks resulted in higher value of true density and compressive strength, with the low amount of water absorption and apparent porosity compare to 850 ℃ of glass bricks.
