CM or as required for the purpose of the investigation. Commercially available standard astmm may be used provided the normality is checked according to the standardization procedure.

Place the beaker on a magnetic stirrer and add a TFE-fluorocarbon coated stir bar. A digital readout is preferred but not required. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old. Dilute to 1 L in a volumetric flask and mix thoroughly.

The volume should not exceed mL. No lubricants shall be used during drilling. A number in parentheses indicates the year of last reapproval. The exact normality shall be calculated from the d1152 of three determinations as follows: Astm c astm normas fibra de vidrio.

ASTM C / CM – 03 Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete

Samples should be oven-dried and ground to pass a No. Print and complete the following order form. The cooling water from core cutting may dissolve some of the chloride. Chemical Society, Washington, DC. NOTE 6—To prevent loss of chloride by volatilization, it is important to keep the astk covered during heating and digestion.


Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C 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. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.

Unless otherwise indicated, astj is intended that all reagents shall conform to the specifications of the Commit- tee onAnalytical Reagents of theAmerican Chemical Society5. Link to Active This link will always route to the current Active version of the standard. Privacy Policy Sensors Sitemap.

Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results. Cover the beaker with a watch glass and allow to stand for 1 to 2 minutes. 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.

Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project aastm and testing response times.

C11522 for this method of sampling are as follows: 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. Record the approximate millivoltmeter reading.

Add 3 drops of methyl orange indicator to the beaker and stir. Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample.

No further reproductions authorized. Disperse the sample with 75 mL of water. Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference.

Page and John S. A superscript epsilon indicates an editorial change since the last revision or reapproval. ICS Number Code Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water. Originally approved in Ten seconds of boiling is sufficient.

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: Such chloride will be detected by the use of this method.

In most cases, acid-soluble chloride is equivalent to total chloride.
