Abstract
The purpose of this project is to study the effect of colouring agent on the corrosion properties of glass composite tiles. The raw material used is waste soda lime silicate glasses (SLSG) which are transparent and green coloured glass. The glass were milled and sieved to < 75 μm and mixed with ball clay that acts as the filler. Waste SLSG (transparent and green) is mixed with ball clay according to the optimum ratio of 90:10 wt. % for transparent GCM and 85:15 wt.% for green GCM. The mixture are then pressed using uniaxial die pressing and sintered at 850⁰C with 1 hour holding time. Water absorption, porosity, and density analyses of both GCM produced are analyzed through ASTM C373. Corrosion analyses are carried out using different types of aqueous solution which are low and high concentration of acid and alkali based on Malaysian Standard (Determination of chemical resistance). The main crystalline phase in both GCM identified using X-ray diffraction (XRD) analysis is quartz (SiO2). Microstructure analysis conducted using scanning electron microscope (SEM) reveals the presence of quartz indicating that crystallise take place during sintering. The physical properties of GCM produced from transparent glass and green coloured glass are 0.06% porosity, 0.03% water absorption, 1.79 g/cm3 of bulk density; and 0.03% porosity, 0.02% water absorption, 2.05 g/cm3 of bulk density; respectively. Highest corrosion rate for both transparent and green coloured GCM is observed after been soaked for 5, 12 and 13 days is Lactic acid solution (high concentration acid). The corrosion rates after 13 days of soaking in the Lactic acid solution are 3.84 mpy for transparent GCM and 3.92 mpy for green coloured GCM.
