ASTM C Test for Chloride in Mortar and Concrete | CTLGroup

Cover the beaker with ast watch glass and allow to stand for 1 to 2 minutes. Page and John S. Order Form 2 Email complete form to contact listed below. Historical Version s – view previous versions of standard.

Some values have only SI units because the inch-pound equivalents are not used in practice. A slurry that is only slightly acidic is sufficient. Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0. Specification D for Type Astmm reagent water. Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample.

ASTM C1152.C1152M – 04 – Acid-Soluble Chloride in Mortar and Concrete

Originally approved in Do not allow sample to boil more than a few seconds See Note 6. Directreading balances shall have a sensitivity not exceeding 0. If you need more info or have any questions, please note the Lab ID number 37 and contact us at:. Note 1 — Sieve size is identified by its standard designation in Specification E The volume should not exceed mL.

Parte 1 v1152 2 Designation: The titration may take place in a solution that contains a small amount of solid matter. NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. Dissolve in water and dilute to exactly 1 L in a volumetric flask and mix thoroughly.


Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in. If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. Conventional two-pan balances shall have ast, maximum sensibility reciprocal of 0. Place the beaker on a magnetic stirrer and add a TFE-fluorocarbon coated stir bar. CM or as required for the purpose of the investigation. Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water.

Use Specification limits in concrete are intended to minimize rebar corrosion.

Treatment c1125 hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference. If the solution above the settled solids is not pink colored, add more nitric acid dropwise while stirring until a pink awtm reddish color persists, then add 10 additional drops of nitric acid and stir.

In most cases, acid-soluble chloride is equivalent to total chloride. Submit the concrete mix design if the results will be expressed as Cl – percentage of cement. ASTM Volume 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.

A superscript epsilon indicates an editorial change since the last revision or reapproval. Make a blank determination using 75 mL of water in place of sample. Samples should be oven-dried and ground to pass a No. ICS Number Code Such chloride will be detected by the use of this method. The cooling water from core cutting may dissolve some of the chloride. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Commit- tee onAnalytical Reagents of theAmerican Chemical Society5.


Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Record the approximate millivoltmeter reading.

Current edition approved Dec. Heat the covered beaker rapidly to boiling and remove from hot plate. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old.

Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample. Dilute to 1 L in a volumetric flask and mix thoroughly. The alternative designation in parentheses is for information only and does not represent a different standard sieve size.

Disperse the sample with 75 mL of water. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results.

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 practices and determine the applicability of regulatory limitations prior to use. The original beaker may be used See Note 7. Link to Active This link will always route to the current Active version of the standard. In most cases, acid-soluble chloride is equivalent to total chloride.

Excessive amounts of acid can satm the silver chloride coating on the silver billet electrode prematurely. Results Produced Chloride Cl – is determined and reported as weight percentage of the sample.
