CLAY-BLENDED SLUDGE AS LIGHTWEIGHT AGGREGATE CONCRETE MATERIAL

The results are presented of an investigation of the use of dewatered sludge mixed with clay for the production of lightweight coarse aggregate for concrete. It was found that incinerated clay-blended sludge produced by firing between 1,050 deg C and 1,080 deg C is a potential material for the production of lightweight aggregate concrete. The aggregate produced from incinerated clay-blended sludge may indicate potential characteristics in fire resistance and thermal insulation of concrete. The pH values of incinerated clay-blended sludges, their particle density, their water absorption, as well as the workability of the fresh concrete made with incinerated clay blended sludge coarse aggregates are discussed.
