Abstract
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.
Highlights
Soils are used as raw materials in construction industries such as bricks, cement, and ceramics, but each has specific characteristics (Al-Owaidi, 2013; Awadh and Al-Owaidi 2020)
In soils prepared for the cement industry, specification is required of silicon and aluminum oxides, and other important secondary oxides
The raw materials are burned after good mixing at high temperatures in kilns for the cement industry (Haldar, 2018, Awadh, S.M. and Al-Owaidi, 2021), where cement compounds are formed, and gypsum is added to them in the final stages
Summary
Soils are used as raw materials in construction industries such as bricks, cement, and ceramics, but each has specific characteristics (Al-Owaidi, 2013; Awadh and Al-Owaidi 2020). In soils prepared for the cement industry, specification is required of silicon and aluminum oxides, and other important secondary oxides. These oxides can be identified through chemical examinations. These oxides, which are present in clays and limestone will react to form clinker compounds (Abdulla and Majeed, 2021, Awadh and Al-Owaidi, 2021). The research aims to study the relationship between some physical and chemical properties of the soil samples and their suitability for use as a raw material for the cement industry
