INTERNATIONAL CEMENT ANALYSIS STUDY. PART 2. MICROSCOPIC ANALYSIS OF CLINKERS

This paper describes the results of a cooperative microscopic analysis by point counting methods of samples of six cement clinkers. Ten laboratories took part in this study. The errors are considered to arise from the counting error, operator error and sampling errors. It was found that the sampling errors and the counting errors were significant, but no evidence of operator error was found. It is concluded that the major within-laboratory error is the counting error the size of which can be calculated by the binomial distribution, and that the major between-laboratory error is the sampling error.
