The research included conducting a study of eight selected soil Stations in the Babylon and Al Qadisiyyah. The main target of the research is to study the physical, chemical, and compressive strength properties of these soils and their suitability for manufacturing ordinary clay bricks. It was found through the evaluation of the soils of the studied samples that their physical properties ranged as follows: the water content (13.52-31.88%) and the grain size analysis of the proportions of sand, silt, and clay as follows: (5-27%) (38-48%) (33-47%), respectively. The values of the Atterberg limits ranged as follows: the plastic limit ratios (13-21%), liquid limit (34-49%), plasticity index (13-28%), and the specific gravity ranged between (2.43-2.67). As for the chemical properties of the studied samples, they consist of a lot of silicates, carbonate calcium, and calcium oxide. Studied samples were characterized by water absorption 15-24%, and the efflorescence is varied from medium, low to nil. The soil samples are consequently considered as a suitable material for the manufacture of ordinary bricks in grades A and B based on Iraqi Standard specifications No. 25.

The research was conducted on nine pits for selected soils in Babylon, in the Al-Kifl region in particular. It aims to find the relationship between the physical and chemical properties of the studied soil and its suitability in the cement industry. Nine samples of different depths were taken with a simple description of the soil in the fieldwork stage. As for the stage of laboratory tests, it included testing the grain size distribution to find the percentage of sand, silt, and clay, and Atterberg limits to find plasticity. It was found through these tests that the soil is silty clay and has low plasticity except for samples no. 5, and 6, which were clayey soil with low plasticity. The relationship between physical properties depends on the property of the grain size distribution, as it is the function of the rest of the properties. Chemical tests of the samples and comparing the ratios of their oxides with the standard specifications of the Kufa plant laboratory turned out to be suitable for the manufacture of ordinary Portland cement, as the study area is considered a good quarry for the clays used in such industries.
