الملخص | This work was carried out in an area located about 10 km south of Al-Hamza District, within Al-Diwanya Governorate. The target of this study is to find out the suitability of the clay deposits in the investigated area for cement industry, and to estimate the reserve of the clay.
The field work included excavation of 28 pits within a net of 100 m x 100 m, with average depth of about 4.0 m. Water depth is about 4.0 m.
One hundred and eight samples were collected and subjected to chemical analysis. The average percentages of the main chemical components in the deposits are:
TiO2 Cl K2O Na2O L.O.I. SO3 MgO CaO Al2O3 Fe2O3 SiO2
0.49 0.18 1.47 1.16 16.51 0.34 6.51 13.49 14.34 7.30 42.88
Four samples analyzed minerogically by XRD, and the analysis showed that the main clay mineral constituents are: Montmorillonite, Kaolinite and palygorskite, and the main non clay mineral is mainly Quartz, Calcite, Feldspar and Gypsum. Silica and Aluminum modulus averages of the investigated area are: 1.97, 1.96 respectively. Five samples were subjected to physical test for bulk density; the results showed that the average is 1.62 gm/cm3, the water table recorded during field work in July is about 4.0 m.
The results showed that the industrial bed, within the investigated area is belonging to the Recent sediments, with average thickness of 4.0 m. without overburden. The estimated reserve | |
