本研究係探討爐渣和飛灰對土壤穩定性之效應。試驗將爐渣或飛灰不等量噴灑於后里紅壤、鳳山黄壤和龍潭紅壤上，使各土壌均含有爐渣或飛灰0.5％，1.0％，1.5％等含量，連同對照的零含量共計21個樣本。測定其團粒穩定度結果發現，隨爐渣處理量的增加，可提高團粒平均粒徑；而飛灰雖和爐渣相同具此效果，但考慮土壤陽離子交換能量時，仍以低處理量爲宜。

The purpose of this paper is to study the effect of slag and that of fly ash on the stability of soils taken from How-lii, Feng-shan and Lurng tarn. The tested soils were sprayed with the slag or the fly ash at four rates, 0, 0.5, 1.0 and 1.5%, respectively. The treated samples were stored in plastic bags for three months. The aggregate stability of the samples were determined. From data obtained, we can find that the log-mean diameters of aggregates increase with the increasing rates of slag or fly ash applied. It implies that the soil stability will increase with the increasing rates of slag or fly ash added. A lower rate of fly ash was recommended for maintaining a higher cation exchange capacity of soils.
