ASTM CCM – 04 – Acid-Soluble Chloride in Mortar and Concrete
ICS Number Code Heat the covered beaker rapidly v1152 boiling and remove from hot plate. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine qstm applicability of regulatory limitations prior to use. Rinse the beaker and the filter paper twice with small portions of water. Some values have only SI units because the inch-pound equivalents are not used in practice.
Ten seconds of boiling is sufficient. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Commit- tee onAnalytical Reagents of theAmerican Chemical Society5. Remove the beaker and wipe the electrodes with absorbent paper.
Record the approximate millivoltmeter reading. This solution is the standard and requires no further standardization.
NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. If you need more info or have any questions, please note the Lab ID number 37 and contact us at: It is the responsibility of the user of this standard to establish appropriate safety and health atm and determine the applicability of regulatory limitations prior to use.
For cement products, chloride can also be reported as percentage of the cement component if the content is provided or determined. Directreading balances shall have a sensitivity not exceeding 0. The original beaker may be used See Note 7. No lubricants shall be used during drilling. These notes and footnotes shall not be considered as requirements of this standard.
Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
The alternative designation in parentheses is for information only and does not represent a different standard sieve size. If you need more info or have any questions, please note the Lab ID number 37 and contact us at:. NOTE 4—Sampling tools may be cleaned with a brush, cloth, ethyl alcohol rinse, water rinse, or other method that will not contaminate the sample. Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C Cover the beaker with a watch glass and allow to stand for 1 to 2 minutes.
Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely. Specification D for Type I reagent water. Dissolve in water and dilute to exactly 1 L in a volumetric flask and mix thoroughly.

If the solution qstm 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. NOTE 5—Slags and slag cements contain sulfide sulfur in concentrations that can interfere with chloride determination unless oxidized with hydrogen peroxide. No further reproductions authorized. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old.
If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. Note 1 — Sieve size is identified by its standard designation in Specification E Clean all sampling tools prior to each sampling operation See Note 4.
Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete. These notes and footnotes shall not be considered as requirements of this standard. Do not allow sample to boil more than a few seconds See Note 6. ASTM Volume Link to Active This link will always route to the current Active version of the standard.
To prevent sample contamination, avoid contact of sample with hands and other sources of perspiration. In most cases, acid-soluble chloride is equivalent to total chloride.
Submit the concrete mix design if the results will be expressed as Cl ast, percentage of cement. The cooling water from core cutting may dissolve asttm of the chloride.
NOTE 6—To prevent loss of chloride by volatilization, it is important to keep the beaker covered during heating and digestion. The exact normality shall be calculated from the average of three determinations as follows: Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample.
