In recent years, the generation of muddy soil from various construction sites has been increasing. This study investigates the relation between the strength and the expansion of muddy soil mixed with steel slug and/or incinerated paper sludge ash, in order to make clear the possibility of the recycling of muddy soil. Also, the California Bearing Ratio test and the hastening aging test are performed. As a result, (1) When the muddy soil mixes with steel slug, the greater the mixing rate of slag, the lower the water content and the higher CBR of the treated soil, (2) The incinerated paper sludge ash has an effect on the reduction of the water content of muddy soil, (3) When the treated soil mixed with non-aging steel slug is cured, expansion and an increase in strength are observed, (4) The amount of expansion of the more fine grain steel slug is large, (5) The amount of expansion of the treated soil using non-aging slug is about 4.4mm (3.5%). And that of soil treated with non-aging slug of 50% by the ratio of weight is less than half.
