- Abstract
- An interlaboratory calibration and analysis has been carried out by ASTM Task Group C01.23.01 to assess the use of quantitative x-ray diffraction analysis to determine the proportion of phases in portland cement clinker. This interlaboratory test provides an estimate of precision and bias in the quantitative phase analysis of some clinker phases in mixtures prepared using calibrating phases. These estimates of precision and bias will be incorporated in a proposed standard test method on quantitative phase analysis of cement and clinker currently being developed by the task group.
