This research aimed to reutilize sediment soil from water supply treatment process and waste glass for developing ecofriendly wall tiles. Different amounts, 30-80% of sediment soil and 10-60% of brown glass cullet were used to develop wall tiles. Specimens were moulded by uniaxial pressing at 100 bars with dimensions of 50x100x7 mm. They all fired at a heating rate of 100o C/h and maximum temperature of 950o C for 1 h. Bending strength and water absorption properties of wall tiles were tested and compared with Thai industrial standard (TIS) 2508-2555. Their properties depended on amounts of sediment soil and glass cullet. The optimal formula contained 30 wt% sediment soil and 60 wt% brown glass cullet was selected. Its bending strength and water absorption achieved Thai industrial standard (TIS) 2508-2555. It can be concluded that reutilizing sediment soil and brown glass cullet for developing eco-friendly wall tiles is feasible.
