| Popis: | 99 The “lateritic soil” is a highly weathering rocks of terrace in Taiwan area. It has been widely used as a back filled material. Slag is the by-product of steel plants. A series of tests was performed to study the engineering properties of slag-lateritic soil mixtures. Results show that these properties are changed with slag content. The specific gravity (Gs) increases when slag content increases. For Atterberg limits, when slag is 0% (totally lateritic soil), there exist maximum plastic index (PI) and liquid limit (LL). According to the compact curves of the standard and modified Proctor tests, the maximum dry unit weight (γd,max) increase when slag content increase to 30%. The swelling test shows a obvious trend that increasing slag content could reduce the amount of swell during soaking. The unconfined compression strength has a clear raise while slag content reaches 30%, and decreases lower than slag content = 0% while slag content = 50%. |
