Sand, Silt, Proctor test and Oedometric test.

Many studies have been conducted these last years to investigate the influence of randomly oriented fibers on the mechanical behavior of soils. Yet, few or no studies investigate the influence of Silt on the mechanical behavior of Sand. Therefore, this experimental work has been performed to investigate the influence of Silt on the mechanical behavior of Sand. This experimental work was conducted while using Oedometric apparatus and Proctor mold. The aim is to gradually increase the Silt percentage (0%; 25%; 50%; and 75%) in the Sand and to gradually investigate its mechanical behavior. For all tests, Compaction and Oedometric curves were derived and their results were compared. The results proved that inclusion of Silt affects compaction and Oedometric behaviour of Sand.
