Additional information
| Significance and Use | ||||||||||
|
5.1 This test method provides a relatively simple and reliable microscopical means of measuring the phase abundance of portland cement clinker (Note 1). Microscopical point counting provides a direct measure of the clinker phase composition in contrast to the calculated Bogue phase composition (Note 2). 5.2 This test method assumes the
operator is qualified to operate a reflected light microscope and
the required accessories, is able to correctly prepare polished
sections and use necessary etchants, and is able to correctly
identify the constituent phases.
5.3 This test method may be used as part of a quality control program in cement manufacturing as well as a troubleshooting tool. Microscopic characterization of clinker phases may also aid in correlating cement properties and cement performance in concrete, to the extent that properties and performance are a function of phase composition. |

1.1 This test method covers a systematic procedure for measuring the percentage volume of the phases in portland cement clinker by microscopy. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.3 The values stated in SI units are to be regarded as the standard. |
