These test methods cover the chemical c11 of hydraulic cements. It is used for detection and compensation of systematic bias. No other units of measurement are included in this standard. Apparatus and materials for the test method include balance, weights, glassware and laboratory containers, desiccators, filter paper, crucibles, and muffle furnace.

The reference cement must have an assigned value for the analyte being determined. Test results from alternative test methods may be used as a basis for acceptance or rejection when it is clear that a cement does or does not meet the specification requirement. Any change in test method procedures from those procedures listed in Sections 7—3 0 requires method qualification in accordance with 5.

Such demonstration may be made concurrently with analysis of the cement being tested. Specific chemical test methods are provided for ease of reference for those desiring to use them. If, however, a blank determination is desired for an alternative test method, one may be used and it need not have been obtained concurrently with the analysis.

If either of the two requirements asstm above are not met, identify and correct any problems or errors found in the procedure. Precision and accuracy results for the seven CRMs used for the accreditation. The reference cement is acceptable if its assigned value agrees with the average referee value within the limits given in column 3 of Table 1.

If the reference cement, as supplied, has no documented guarantee of homogeneity, establish its homogeneity by analyzing at least six randomly selected samples.

It is the responsibility of the user of this standard to establish appropriate safety and health practices zstm determine the applicability of regulatory limitations prior to use. The average of those duplicates helps to determine the accuracy results. Reference test methods and procedures include determination of insoluble residue, silicon dioxide, ammonium hydroxide group, ferric oxide, phosphorus pentoxide, titanium dioxide, zinc oxide, aluminum oxide, calcium oxide, magnesium oxide, sulfur, loss on ignition, sodium and potassium oxides, manganic oxide, chloride, chloroform-soluble organic substances.

Last previous edition approved in c1114 C — When a lesser number of CRM cements are required, all of the values shall be within the prescribed limits. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. When reporting the results of referee analyses, specify which test methods were used.

The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements and are also required for referee analysis in those cases where conformance to chemical specification requirements are questioned.

Active view current version of standard. No other units of measurement are included in this standard. Cancel reply to comment.

The final results, when corrected for blank values, should, in either case, be so designated. To demonstrate traceability for a given analyte, perform a referee analysis as defined in 4. CO 2 Determinations in Hydraulic Cements.

ASTM C – 15 – Chemical Analysis of Hydraulic Cement –

Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee aatm certification purposes, as explained in Section 4.

This is the possibility of using fusion as a rapid test method if the resulting differences are found to be below the allowed values specified by ASTM C for the suitable elements. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting procedures. Specific chemical test methods are grouped as reference test methods and asstm test methods. Standard A by the mass fraction of Standard A in each of the other standards that is, 0.

Private Feedback to AZoM. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 3.

CO2 from the certificate value by the mass fraction of Certified CaCO3 added to that c14 percentage added divided by ; multiply the value determined for. A CRM sample weighing 0. CO 2 Determinations in Hydraulic Cements. Longer, more complex procedures, in some instances, have been retained as alternative asrm methods to permit comparison of results by different procedures or for use when unusual materials are being examined, where unusual interferences may be asrm, or when unusual preparation for analysis is required.

Cement industries, including various other factories that manufacture products from raw materials, are expected to meet extremely rigorous quality standards.

When Reference Methods are used, qualification testing of the analyst is required as described in 5. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4.

When a blank determination See Note 1 i s specified, one shall be made with each individual analysis or with each group of two or more samples analyzed on f114 same day for a given analyte. The average of all the standard materials are listed based on the accuracy and precision of the related element. The XRF analysis was performed by an independent mineral laboratory Corem. Duplicate samples shall be tested on different days. Recommended Order for Reporting Analyses.

Given below are seven Portland cement CRMs that have all the target elements essential for this study. Originally approved in Traceability consists of documentary evidence that the assigned values of the reference.
