AB - The effect of bloating and fluxing agent on the microstructure and physical properties were studied in manufacturing the artificial lightweight aggregates of bulk density below 1 using clay and stone sludge. In case of the aggregates added only with bloating agent, the bulk density and water absorption were 0.5~1.0 and 41~110 % respectively but the microstucture was not uniform with a rough appearance. For the aggregates added with a fluxing agent and one bloating agent, a part of shell was lost due to explosion of specimen caused by over-bloating during a sintering. The mixed addition of bloating agents with vacuum oil, carbon and Fe2O3 made the microstructure homogeneous by generating an uniform black core and shell structure. The aggregates added with mixed agents and sintered at 1200oC showed the bulk
density 67 % lower and water absorption 48 times higher than those of the specimen with no additives. In this study, the artificial lightweight aggregates showing the bulk density of 0.5~1.0 and water absorption of 50~125 % could be fabricated to apply to various fields.
