A cement shall not be rejected for failure to conform to chemical requirements unless all determinations of constituents involved and all necessary asstm prior to the determination of any one constituent are made entirely by these methods.

ASTM C – 18 Standard Test Methods for Chemical Analysis of Hydraulic Cement
In this interview, AZoM talks aatm Dr. Link to Active This link will always route to the current Active version of the standard. No other units of measurement are included in this standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
When Reference Methods are used, qualification testing of the analyst is required as described in 5. Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this standard to establish appropriate safety and asstm practices and determine the applicability of regulatory limitations prior to use.
ASTM C114 – 15 – Chemical Analysis of Hydraulic Cement
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This standard is dedicated to the analysis of hydraulic cement. A CRM sample weighing 0.
The XRF analysis was performed by an independent mineral laboratory Corem. Changes that occur during the fabrication process can influence the physical properties of the final products. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting c114. A number in parentheses indicates the year of last reapproval.
When an average of either two or three results can be calculated, the calculation shall be based on the three results. Acceptable reference cements are NIST.
Material CRM must be used in the qualification of test methods and analysts. Katanax X Electric Fluxer.
This abstract is a brief summary of the referenced standard. Longer, more complex procedures, in some instances, have been retained as alternative test methods to permit comparison of results by different procedures or for use when unusual materials are being examined, where unusual interferences may be suspected, or when unusual preparation for analysis is required. Standard A by the mass fraction of Standard A in each of the other standards that is, 0.
When a lesser number of CRM cements are required, all of the values shall be within the prescribed limits. A When seven CRM cements are required, as for demonstrating the performance of rapid test methods, at least six of the seven shall be within the prescribed limits and the seventh shall differ by no more than twice that value.
CO 2 Determinations in Hydraulic Cements.
ASTM C – 15 – Chemical Analysis of Hydraulic Cement –
A reference sstm method must be used where an alternative test method is not provided. It is used for detection and compensation of systematic bias. Requalification of the analyst is required every v114 years. Given below are seven Portland cement CRMs that have all the target elements essential for this study.
ASTM does not give any warranty express or implied or make any representation that the c1114 of this abstract are accurate, complete or up to date. Prepare three standards, each in duplicate: General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation.
No other units of measurement are included in this standard. Originally approved in Table 2 also shows the results derived for the standards used to perform the test.
The final results, when corrected for blank values, should, in either case, be so designated. The individual analyst must demonstrate achievement of acceptable precision and bias, as explained in Section 3, when these test methods are used.
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 x114 the same day for a given analyte.
When Rapid Methods are used, qualification testing of both the analyst and the test method are asm as described in 5. Active view current version of standard. Any change in test method procedures from those procedures listed in Sections 7—3 0 requires method qualification in accordance with 5.
Specific chemical test methods are provided for ease of reference for those desiring to use them. Sample preparation and general test procedures shall be followed according to the specification. A ”rapid test method” can be used if the difference in results complies to the limitation projected by this norm. The alternative test methods generally provide individual determination of specific components and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and c1144 indicated in the individual method.
The analyst is considered qualified when the difference between the duplicate results does not vary by more than the value listed in Column 2 of Table 1 and the average of the two samples agrees with the certificate value of the CRM within the limits listed in Column 3 of Table 1 after correction for minor components when needed.
