Blended Pozzolan for Use in Concrete58.1 Ensure that blended pozzolan conforms to the chemicaland physical requirements as prescribed in the tables ofSpecification C 618. The purchaser will sp

17、ecify the mineraladmixture class (in Specification C 618). Carbon may substi-tute for loss on ignition requirement. The percentage of carbonor loss on ignition is determined by the procedure in the sectionon test methods.9. Sampling9.1 Sample the blended pozzolan in accordance with therequirements o

Determine total loss on ignition according to TestMethods C311except use platinum crucibles and ignite at atemperatu

20、re of 950 6 50C. Calculate total loss on ignitionaccording to Test Methods C311. The total loss in weight isassumed 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 ha

21、ve negligible amounts of carbondioxide.10.2.1.2 Report loss on ignition (corrected for CO2) forblended pozzolan 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

22、dioxide.10.2.2 Determination of carbon (corrected for CO2)inblended pozzolan is an acceptable alternative to loss 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

23、 sampleof blended pozzolan according to Test Methods C25. Reportcarbon corrected for CO2for blended pozzolan as the differ-ence between total carbon and carbon dioxide. Thus, thepercentage carbon (corrected for CO2) = the percentage totalcarbon (CO23 0.273).10.2.3 Determine non-carbonate carbon usin

QUALITY ASSURANCE PROGRAM: ADEQUACY OF THE BLENDING PROCESS AT THE PRODUCTION FACILITYX1.1 A blend of two

34、 ingredients of different absolutedensities should result in a known reproducible density foreach proportion. For 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 afte

35、r the blending process has beencompleted and determine the densities of each.X1.2 To complete the testing for blending 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

36、of material,mix, and add the bag to the 12-ton batch) and after the blendingprocess is completed. The concentration 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 wei

37、ghts, blending times, blending procedure,and other pertinent data.X1.4 The check for the uniformity of the blend 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

38、 of any patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject
