Physical and Mechanical Properties of Sintered Clay Body Mixed with Sewage Sludge

Abstract

Physical and mechanical properties including volume density, compressive strength and linear shrinkage of sintered clay body (SCB) mixed with sewage sludge incineration ash (SSIA) at the highest calcination temperature of 1050°C have been investigated. The result shows that 40% is the maximum percentage of SSIA in the SCB for meeting the compressive strength MU10 in the national standard GB5101-2003.
