CEMENT ANALYSIS BY MEANS OF ATOMIC ABSORPTION SPECTROMETRY

ANALYSE DES CIMENTS PAR SPECTROMETRIE D'ABSORPTION ATOMIQUE

THE ATOMIC ABSORPTION SPECTROMETRY METHOD, AFTER A SOLUTION HAS BEEN OBTAINED WITH DILUTED HYDROCHLORIC ACID, CAN BE APPLIED TO THE ROUTINE CONTROL OF SYNTHETIC AND SLAG PORTLAND CEMENT. DETAILS ARE GIVEN OF THE ANALYTICAL METHODS OF STUDYING PARAMETERS. EXAMPLES OF TEST PROCEDURES ARE ALSO GIVEN. MEASUREMENTS ARE MADE AFTER ADEQUATE DILUTION BY COMPARISON WITH A STANDARD CEMENT. THE REPRODUCIBILITY OF THE MEASUREMENTS IS EXAMINED BY CONSIDERING THE RESULTS OF APPROXIMATELY 100 ROUTINE ANALYSES. MEAN VARIATION COEFFICIENTS ARE APPROXIMATELY 0,4% FOR ALL ELEMENTS EXCEPT ALUMINA FOR WHICH THE COEFFICIENT VALUE IS 1,1%. THE ACCURACY OF THE RESULTS IS EVALUATED BY COMPARING THE LATTER TO THE MEAN VALUES OBTAINED DURING TESTS AT THE LCPC AND CERILH LABORATORIES. THIS METHOD IS PARTICULARLY SIMPLE TO APPLY, SHORTER THAN CONVENTIONAL METHODS AND OF A VERY LOW COST. IT IS AT THE ACCEPTANCE TEST LEVEL.
