| Abstract | ||
| Geochemical analysis, mineralogical, petrographic and petrophysical studies were carried on samples of limestone rocks have been collected from four selected outcrops on the eastern side of Makhul anticline, between Qasr AlJabbar and Al_Musallakhah localities within the Fat'ha formation, to assess the suitability of limestone as a major component of the mixture of raw materials for the cement manufacturing. The results show low percent of calcium oxide and high percent of magnesium oxide, which makes the materials unsuitable in terms of chemical composition. The percentages of silica, alumina, iron oxides, sulfate and alkali, within the limits allowed for this industry. The mineralogical study proved the presence of calcite and the prevalence of dolomite, which cause the increasing of MgO. The presence of clay minerals of Kaolinite, Palygorskite, and Montmorelonite also proved. The petrographic studies show the effect of the dissolution which lead to increase the porosity. The study confirm the impact of the dolomitization, also, it's proved that the effect of neomorphism more than the cementation in the rock samples. The petrophysical studies of samples indicate high porosity and low compressive strength, density and moisture content, which make the rocks more friable and easy for crushing and grinding during the preparation of the mixture. Thus, the limestone in the studied area is unsuitable as raw materials for the cement manufacturing, unless adding of special additives or modify the rates of oxides. | ||
