| Abstract | ||
| This study deals with the physical properties of Quaternary sediments in the middle part of Erbil Plain, which is about 1670 Km²; Quaternary sediments, cover about 85% of the studied area. For consistency of soil and clay mineral tests, sixteen localities were selected in different parts of the studied area; GPS instrument was used for indicating the precise location. The flow curve of Atterberg limits (liquid and plastic limits) indicated that generally the majority of the samples show low to medium plasticity index, between 6.7 – 19.1. However, some localities, particularly near the building of Construction Laboratories, have high plasticity index, which is 26. The XRD analysis of the samples indicates that the samples contain quartz and calcite; the clay minerals are montmorillonite, illite and kaolinite. The percentage of these clay minerals was calculated and showed that in some areas like Hasarok, Daratu and Bestana the soil should be taken into consideration for any construction and might need soil improvement, because they include high percentage of montmorillonite and expansive clay, which are not suitable for heavy constructions and need soil improvement. | ||
