چکیده

در این پژوهش کانی­شناسی، ژئوشیمی و تصاویر SEM کلینکر و سیمان پرتلند کارخانه­ی سیمان ارومیه با استفاده از مقاطع صیقلی و تصاویر SEM کلینکر و نیز آنالیز شیمیایی سیمان و کلینکر به روش XRF در آزمایشگاه شیمی کارخانه سیمان ارومیه بررسی شد. شاخص­های بوگه محاسبه شدند و برای مقایسه­ی سیمان و کلینکر ارومیه با استاندارد جهانی از شاخص اشباع آهک، نسبت سیلیس و آلومینیوم نیز استفاده و موقعیت کلینکر و سیمان­های پرتلند در نمودارهای فازی مختلف نشان داده شد. نتایج نشان دهنده­ی وجود فازهای آلیت، بلیت، کوارتز و آلومینات در مقاطع صیقلی است، سوخت لازم از نوع میادین گازی است، سرعت بالا رفتن گرما در کوره و سرعت سرد شدن کلینکر ضعیف است، پخت کلینکر در زمان نسبتاً طولانی صورت گرفت و معلوم شد کلینکر و سیمان پرتلند نوع 2 ارومیه با استاندارد کلینکر و سیمان جهان همخوانی دارند.

چکیده [English]

In this research, mineralogy, geochemistry and SEM micrographs of clinker and Portland cement of Orumiyeh Cement factory were studied by Clinkers Polished sections and SEM micrographs as well as chemical analysis of clinker and Portland cements were done by XRF method in the Orumiyeh cement factory chemical lab and bogue chemical indices were calculated. Also, lime saturation factor, silica and alumina ratios were also used to compare the Orumiyeh cements and clinker by universal standards. The results show the presence of alite, belite, quartz and aluminate phases in polished sections, the necessary fuel is a type of gas fields, the rate of increasing the temperature in the kiln is very much, the rate of cooling is weak and burning the clinker has been performed during a long time. Also the Orumiyeh clinker and Portland cement type 2 have significant conformation to clinker and cement universal standards
