ASTM C1365

Proportion of Phases in Portland Cement and Portland-Cement Clinker Using X-Ray Powder Diffraction Analysis

Applicability: ASTM C1365 is a standard test method for determining the proportion of individual phases in Portland cement and Portland-cement clinker using quantitative X-ray diffraction analysis (QXRD). It’s primarily used in quality control during cement manufacturing and in predicting the properties of hydrated cement and concrete.

Purpose: ASTM C1365 is a standard test method used to determine the proportion of crystalline phases in portland cement and portland-cement clinker using X-ray powder diffraction analysis. This standard specifically identifies and quantifies phases like alite, belite, aluminate, ferrite, periclase, gypsum, bassanite, anhydrite, and calcite.
