In this paper, the first part discusses the engineering characteristics of granulated slag as a soil material and the second deals with some applications of it in the fields. (1) The weight per unit volume of this slag is 1.2~1.4 (g/cm3), which is about 70% as compared with that of a natural soil. The low density depends on the slag particle which has many pores inside. (2) The coefficient of permeability of the slag is 1.0 × 10-1~10-2(cm/sec), so that the slag can be used as a soil material with high drainage. (3) The angle of internal friction is more than 35°, which depends on the degree of compaction. The slag particles are normally angular and grip well each other. (4) The slag has the character of self-hardening with time and it is promoted easily by the help of alkali as a lime. Thus the slag can be used as a cohesive sandy material. The granulated slag, which has the above characteristics, can be used for the materials of embankment on soft clay ground, basement of road, stabilization of slope, back-filling of retaining wall and so on. Some examples of the site uses and designs of the granulated slag were also given.
