Nyazi s.abdealradh@ukh.edu.krd <p>The Pila Spi Formation is exposed in Permam Mountain forming its carapace, and continuous ridges for few hundreds of&nbsp;kilometers. The rocks of the formation are mainly dolomitic limestone, dolomite, and limestone with various proportions.&nbsp;The thickness of the formation in Permam Mountain is about 100 m. Nine samples are collected from the Pila Spi Formation&nbsp;along a recently road cut across Permam Mountain. The sampling interval varies from 10 to 15 m. The collected samples&nbsp;were subjected to X-ray fluorescence (XRF) spectroscopy test to indicate the percentages of the main oxides in the samples.&nbsp;The results showed that the chemical composition of samples No. 1 and 9 meet the Iraqi standards for cement industry,&nbsp;whereas the remaining samples (Nos. 2–8) do not meet the Iraqi standards, and their total thickness is 80 m. To evaluate the&nbsp;suitability of the exposed rocks for cement industry in the sampled section within the Pila Spi Formation, different ratios of&nbsp;sample No. 1 were mixed with different ratios of a sample called sample No. A, it represents a mixture of samples No. 2–8.&nbsp;The mixing ratios are: (Sample No. 1/sample No. A) 50/50, 60/40, 70/30, 80/20, and 90/10. The same procedure was&nbsp;repeated for Sample No. 9. Another attempt was performed by mixing equal ratios of samples Nos. 1 and 9 with the same&nbsp;performed ratios with sample No. A.The chemical compositions of the samples were indicated using XRF test. The results&nbsp;showed that the best mixing ratios for the cement industry are 90:10, 80:20, and 70: 30 (samples Nos. 1+9: sample No. A).</p> 2019-03-01T00:00:00+03:00 ##submission.copyrightStatement##
