Compression Characteristics of Industrial Solid Waste

The increasing demand for building materials in the road industry creates demand for more high-quality aggregates. In order to conserve natural resources, more attention is focused on anthropogenic soils and industrial solid wastes. For the successful application of anthropogenic soils, a series of geotechnical tests have to be conducted. In this article, the results of the oedometric test on the Industrial Solid Waste (ISW) are presented. The tests were conducted on the two types of ISW, the Boiler Slag and Bottom Ash mix (BS+BA) and blast furnace slag. The test results show acceptable compression characteristics which are in the range of natural aggregates. The compaction effort resulted in the preconsolidation pressure occurrence, which was observed during the oedometric test. The compression index and recompression index value show that the compression characteristics is close to the loose and dense sand.
