Manufacturing of Construction Materials from Municipal Incinerator Residue

Article Preview

Municipal incinerator residue (MIR) was used as raw material to replace clay to manufacture bricks. Brick specimens were substituted from 0 to 50 wt% MIR by 10 wt% increment for clay. Clay-MIR brick specimens were fired at 800~1050°C for 2 h. Firing shrinkage, bulk density, water absorption rate and compressive strength were investigated. Leaching procedure tests were also conducted to characterize toxicity. Increasing MIR contents resulted in a decrease in water absorption rate, firing shrinkage and increase in compressive strength of bricks. It was found that when brick specimen with 50 wt% of MIR content was heat-treated at 1000°C for 2 h, a brick specimen could be generated, which was compressive strength of 1256 kg/cm2, water absorption ratio of 6.8% and firing shrinkage of 3.5%. This indicates that MIR is indeed suitable for the partial replacement of clay in bricks
