AB - The artificial aggregates (AAs) composing of 2 wastes, coal bottom ash and dredged soil (7 : 3, weight ratio)were fabricated as a function of red mud contents, 0~30 wt% using direct sintering method at 1050~1250oC for 10 min,and those physical properties were evaluated. Especially, in order to analyze the red mud addition effect on the bloating phenomenon of AAs manufactured, the specific gravity and water absorption were measured and studied linked with the microstructural observation results. The lightening of AAs was enhanced due to increased bloating with increasing temperature and red mud contents. The AAS sintered at 1050~1150oC showed well-developed black-coring structure, but for the specimens containing red mud sintered over 1200oC generated excessive liquid and gas caused by reduction of Fe2O3, thus the black-coring part was gradually burst open out of shell of AAs. Particularly, all specimens containing 30 wt% red mud was burst up when sintered over 1100oC. The AAs containing no red mud sintered at 1200oC had a specific gravity of about 1.2 and those containing 20 wt% had below 1.0 which are characters of lightweight aggregate.
