The ALAs of 100% dredged soil showed the black core phenomenon even at the low sintering temperature as 1050 degrees C and become lightened by bloating pores in black core area with sintering temperature. On the other hand, the aggregates with 100% waste catalyst slag did not showed black coring and bloating phenomenon and had the low forming ability and many cracks inside. Adding the dredged soil to the waste catalyst slag decrease the specific gravity by promoting the black coring and bloating inside. The water absorption(%) of ALAs decreased with sintering temperature. The ALAs fabricated in this study showed the specific gravity of 0.8 similar to 2.0 and water absorption of 2 similar to 16% so,it could be applied to various fields such as the lightweight concrete or the field of the porous carriers for purification of a contaminated soil or water.
