تحديد نسب الأطوار لبعض أنواع الاسمنت المنتج في اليمن و المستورد، بطريقة حيود الأشعة السينية XRD

Abstract EN

A study has been conducted to analyse the phase composition of produced and imported cement in Yemen.The present study is based on eight cement samples representing four produced cements in Yemeni factories and the other four were imported.

The cement samples were subjected to various tests using X-ray diffraction (XRD) with Diffractometer D5000 manufactured by Siemens, and was calculated with the help of the software TOPAS (from the company BRUKER-AXS) in the Finger institut (Bauhaus University Weimar). Generally, the tests show that 7 samples are responding to the requirements for use in building construction, and only one sample (namely, MA7) is not satissfactory and has anexpected pre-crushing test failure. The researcher suggests some recommendations according to the study results so as to ensure optimal use of cements for the construction industry in Yemen.
