Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.

Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample. Parte 1 de 2 Designation: These notes and footnotes shall not be considered as requirements of this standard. The astmm designation in parentheses is for information only and does not represent a different standard sieve size. Link to Active Axtm link will always route to the current Active version of the standard.

Page and John S. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old.

If the solution above the settled solids is not pink colored, add more nitric acid dropwise while stirring until a pink or reddish color persists, then add 10 additional drops of nitric acid and stir. Print and complete the following order form. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results.

Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes. Some values have only SI units because the inch-pound equivalents are not used in practice.

However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of 1c152 in the very alkaline cement system. The original beaker may be used See Note 7. The titration may take place in c1512 solution that contains a small amount of solid matter.

NOTE 7—It is not necessary to clean all the slurry residue from the sides of the beaker, nor is it necessary that the filter remove all the fine material. Privacy Policy Sensors Sitemap. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but aastm not provided as part of the standard. CM or as required for the purpose of the investigation. A superscript epsilon indicates an editorial change since the last revision or reapproval.

Clean all sampling tools prior to each sampling operation See Note 4. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference. Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0.

Note 1 — Sieve size is identified by its standard designation in Specification E Ten seconds of boiling is sufficient. In most cases, acid-soluble chloride is equivalent to total chloride. Procedures for this method of sampling are as follows: Record adtm approximate millivoltmeter reading. The volume should not exceed mL. The exact asgm shall be calculated from the average of three determinations as follows: A number in parentheses indicates the year of last reapproval.

Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Heat the covered beaker rapidly to boiling and remove from hot plate. Some values have only SI units because the inch-pound equivalents are not used in practice.

Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference. Submit the concrete mix design if the results will be expressed as Cl – percentage of cement. Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure. For cement products, chloride can also be reported as percentage of the cement component if the content is provided or determined.

Thus, astj such samples asm be combined, or the data used with care. Cover the beaker with a watch glass and allow to stand for 1 to 2 minutes.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in the very alkaline cement system.

Directreading balances shall have a sensitivity not exceeding 0. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Astn tee onAnalytical Reagents of theAmerican Chemical Society5. Astm c astm normas fibra de vidrio. ASTM Volume Add 3 drops of methyl orange indicator to the beaker and stir.

Rinse the beaker and the filter paper twice with small portions of water. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The alternative designation in parentheses is for information only and does not represent a different standard sieve size. In most cases, acid-soluble chloride is equivalent to total chloride. Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete.
