Abstract
This study investigated the use of water treatment sludge to replace cement in the production of paving tiles for external use. The study utilized sludge-cement replacement percentages of 10%, 20%, 30%, 40% and 50%. Produced tiles were tested for water absorption and breaking (bending) strength. Leaching of sludge metals from tiles was assessed using TCLP. The study showed that all produced tiles exhibited a water
absorption ratio of around 10%. The study concluded that produced tiles, except for 50% sludge-cement replacement, comply with the breaking strength requirements of 2.8 MPa for tiles for external use. The TCLP results indicated that metal leaching from tiles is negligible.
