Physical, Chemical and Morphological Characterization for Problematic Field Soil in Kirkuk City, Iraq
One of the most important problems in geotechnical aspects is sudden failures and cracks in any buildings on the site. Furthermore, it is known in the construction field that clay is a difficult soil and possible explanations for this phenomenon include low strength, high compressibility, large volumetric changes, and a high tendency to swelling and swelling of soil particle size. Chemical and physical characteristics are what control the properties of clay soil and the changes that occur when it comes into contact with water. When faced with the situation, the sample is examined based on the microstructure of the clay. Thus, the study highlights the importance of physicochemical and morphological characterization and the shape and size of soil particles by scanning electron microscopy (SEM) and X-ray diffraction (XRD) in identifying problematic field soils for buildings with cracks at the project site in the city of Kirkuk, Iraq. Soil samples were collected from the field at a depth of 2 m, where various experimental tests were applied to determine the various soil properties, demonstrate the structure of the soil, and examine the main causes of such defects in the building. SEM imaging of the inspected sample objects indicated that the texture of the soil included lots of hollows, and this means that the soil has many not regular apertures. In addition, TEM results emphasized substantial disparities in the coherence of the particles, ranging between 2 – 20 µm. Aside from that, results of the XRD examination also confirmed that this soil has a high proportion of quartz and calcium compared to other minerals. This study revealed that there is an extremely high density of calcium sulfate carbonates which are exceeding the recommended standards. As the result of the study, the researchers detected that the allowable sulfate had been exceeded.
