A method for the determination of some minor compounds in portland cement and clinker by X-ray diffraction

Abstract

This paper describes a method of removal of the silicate phases in cements and clinkers by leaching with a maleic acid-methanol solution. Quantitative and qualitative determinations by x-ray diffraction can be made on the minor compounds remaining after separation. These compounds include the ferrite phases (C6A2F, C4AF, C6AF2 and C2F), C3A, NC8A3, C4A3S, and MgO periclase. The paper discusses techniques used, pure compounds manufactured and calibration curves contructed. © 1974.
