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. These notes and footnotes shall not be considered as requirements of this standard.
Ten seconds of boiling is sufficient. In most cases, acid-soluble chloride is equivalent to total chloride. Disperse the sample with 75 mL of water. 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. Heat the covered beaker rapidly to boiling and remove from hot plate. Page and John S. Conventional two-pan balances shall have a maximum sensibility reciprocal of 0.
ASTM Volume No lubricants shall be used during drilling. Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water. NOTE 6—To prevent loss of chloride by volatilization, it is important to keep the beaker covered during heating and digestion.
Originally approved in NOTE 9—If the tip of the buret is out of the solution, any adhering droplet should be rinsed into the beaker with a few millilitres of water following each titration increment.
ASTM C1152.C1152M – 04 – Acid-Soluble Chloride in Mortar and Concrete
Directreading balances shall have a sensitivity not exceeding 0. Some values have only SI units because the inch-pound equivalents are not used in practice. Parte 1 de 2 Designation: 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: Chemical Society, Washington, DC.
Dilute to 1 L in a volumetric flask and mix thoroughly.

Make a blank determination using 75 mL of water in place of sample. Add 3 drops of methyl orange indicator to the beaker and stir. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
If you need more info or have any questions, please note the Lab ID number 37 and contact us at:.
If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. The original beaker may be used See Note 7.
The cooling water from core cutting may dissolve some of the chloride. Remove the beaker and wipe the electrodes with absorbent paper. Record the approximate millivoltmeter reading.
Current edition approved Dec.
NOTE 5—Slags and slag cements contain sulfide sulfur in concentrations that can interfere with chloride astmm unless oxidized with hydrogen peroxide.
Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in. Some values have only SI units because the inch-pound equivalents are not used in practice. Time for Cc1152 Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Use Specification limits in concrete are intended to minimize rebar corrosion.
Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes. The alternative designation in parentheses is for information only and does not represent a different standard sieve size. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to c1125 its use without lessening the accuracy of the determination.
Submit the concrete mix design if the results will be expressed as Cl – percentage of cement. Astm c astm normas fibra de vidrio. Astm a Astm a Cover the beaker with a wstm glass and allow to stand for 1 to 2 minutes. Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample.
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.
