16、NOTE 2Certain raw materials like fly ash and cement kiln dust, whichblends are covered by this specification, vary from source to source, aswell as within sources.7. Blended Pozzolan for Use with Lime47.1 Ensure that blended pozzolan conforms to the require-ments prescribed in Specification C593.8.
17、Blended Pozzolan for Use in Concrete58.1 Ensure that blended pozzolan conforms to the chemicaland physical requirements as prescribed in the tables ofSpecification C618. The purchaser will specify the mineraladmixture class (in Specification C618). Carbon may substitutefor loss on ignition requireme
18、nt. The percentage of carbon orloss on ignition is determined by the procedure in the sectionon test methods.9. Sampling9.1 Sample the blended pozzolan in accordance with therequirements of Test Methods C311.10. Test Methods10.1 Blended Pozzolans for Use With LimeUse test meth-ods as required in Spe

Ignite the oven
20、-dried blended pozzolan in a muffle furnace at a controlledtemperature. Determine total loss on ignition according to TestMethods C311 except use platinum crucibles and ignite at atemperature of 950 6 50C. Calculate total loss on ignitionaccording to Test Methods C311. The total loss in weight isass
21、umed to be CO2, C, and any chemically combined water.10.2.1.1 Determine carbon dioxide on an oven-dried sampleof blended pozzolan according to Test Methods C25. Someblended pozzolans may have negligible amounts of carbondioxide.10.2.1.2 Report loss on ignition (corrected for CO2) forblended pozzolan
22、 as the difference between total loss onignition and carbon dioxide. Thus, the percentage loss onignition (corrected for CO2) = the percentage total loss onignition minus percentage carbon dioxide.10.2.2 Determination of carbon (corrected for CO2)inblended pozzolan is an acceptable alternative to lo
23、ss onignition (corrected for CO2).10.2.2.1 Determine total carbon on an oven-dried sample ofblended pozzolan according to Test Methods C25.10.2.2.2 Determine carbon dioxide on an oven-dried sampleof blended pozzolan according to Test Methods C25. Reportcarbon corrected for CO2for blended pozzolan as
24、 the differ-ence between total carbon and carbon dioxide. Thus, thepercentage carbon (corrected for CO2) = the percentage totalcarbon (CO2 0.273).10.2.3 Determine non-carbonate carbon using test methodEPA 9060.11. Storage and Inspection11.1 Store the blended pozzolan in such a manner as topermit eas
25、y access for proper inspection and identification ofeach shipment. The purchaser shall have access to everyfacility for careful sampling and inspection, either at the sourceor at the site of the work as may be specified by the purchaser.12. Rejection12.1 Material that fails to conform to the require
26、ments ofthis specification may be rejected. Report rejection to theproducer or supplier promptly and in writing. In case ofdissatisfaction with the results of the test, the producer orsupplier may make claim for a rehearing.12.2 Packages more than 2 % below the weight markedthereon, may be rejected;
27、 and if the average weight of thepackages in any shipment, as shown by weighing 50 packagestaken at random, is less than that marked on the packages, theentire shipment may be rejected.12.3 Blended pozzolan remaining in storage for a periodgreater than 6 months after completion of the tests may bere
28、tested and may be rejected if it fails to conform to any of therequirements of this specification.13. Certification13.1 When specified in the purchase order or contract,furnish the purchaser certification that samples representingeach lot have been tested or inspected as directed in thisspecificatio
29、n and the requirements of this specification havebeen met.13.1.1 When specified in the purchase order or contract,furnish a report of the test results that contain the results ofchemical analysis of the blended pozzolan to provide thepurchaser the composition of the material. Include in thatanalysis

QUALITY ASSURANCE PROGRAM: ADEQUACY OF THE BLENDING PROCESS AT THE PRODUCTION FACILITYX1.1 A blend of two ingredients of different absolutedensities should result in a known reproducible density foreach proportion. Fo
35、r example, a uniform blend of 80 % fly ash(density = 2.27) and 20 % kiln dust (density = 2.9) shouldresult in a density within 5 % of the theoretical density. Takethree random samples after the blending process has beencompleted and determine the densities of each.X1.2 To complete the testing for bl
36、ending uniformity, onecan determine the distribution of a very small quantity ofadmixture within the products. Add fluorescein to the batch(for example, add 30 g fluorescein to a 5-lb bag of material,mix, and add the bag to the 12-ton batch) and after the blendingprocess is completed. The concentrat
37、ion of fluorescein in thebatch, as measured by spectrophotometric technique, should be95 to 105 % of theoretical.X1.3 The exact blending process must be in the QA reportincluding batch weights, blending times, blending procedure,and other pertinent data.X1.4 The check for the uniformity of the blend
38、 should beperformed on a monthly basis or each time the blendingprocess varies (equipment, blending time, weights, and soforth).ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
