EFFECT OF SOAKING ON THE COMPACTION CHARACTERISTICS OF AL-NAJAF SAND SOIL

Abstract

The process of salt dissolution is a reason of structure severe deformation by effective settlement. This paper investigates the effect of soaking process on the soil samples from site near the Faculty of Engineering at University of Kufa. Four samples (S1, S2, S3 and S4) were taken from different locations near the selected site. These samples were soaked for two weeks' duration then tested with standard Proctor to estimate the change in the maximum dry density with reference one (natural samples). All samples experience an increase in the maximum dry density and this increase varies
