Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results.
ASTM C Test for Chloride in Mortar and Concrete | CTLGroup
Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.
Heat the covered beaker rapidly to boiling and remove from hot plate. Chemical Society, Washington, DC. ASTM Volume asfm Place the delivery tip of the 10 mL buret filled to aztm zero mark with standardized 0. 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. No lubricants shall be used during drilling. Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water.
ASTM C1152.C1152M – 04 – Acid-Soluble Chloride in Mortar and Concrete
Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference. Order Form 2 Email complete form to contact listed below.
X1152 the approximate millivoltmeter reading. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results.
Parte 1 de 2 Designation: Astm a Astm a Do not allow sample to boil more than a few seconds See Note 6. Directreading balances shall have a sensitivity not exceeding 0. If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. For cement products, chloride can also be reported as percentage of the asgm component if the content is provided or determined. Clean all sampling tools prior to each sampling operation See Note 4. Specification D for Type I reagent water.
Make a blank determination using 75 mL of water in place of sample. Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely. If you need more info or have any questions, please note the Lab ID number 37 and v1152 us at: 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.
In most cases, acid-soluble chloride is equivalent to total chloride.
Results Produced Chloride Cl – is determined and reported as weight percentage of the sample. Note 1 — Sieve size is identified by its standard designation in Specification E A digital readout is preferred but not required.
