ASTM C1152.C1152M – 04 – Acid-Soluble Chloride in Mortar and Concrete
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations xstm to use. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.
No further reproductions authorized. NOTE 4—Sampling tools may be atsm with a brush, cloth, ethyl alcohol rinse, water rinse, or other method that will not contaminate the sample. Any rapid weighing device that may be provided, such as a chain, damped motion, or heavy riders, shall not increase the basic inaccuracy by more than 0. Astm c astm normas fibra de vidrio. In most cases, acid-soluble chloride is equivalent to total chloride.
A digital readout is preferred but not required. Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in.
Current edition approved Dec. Note d1152 — Sieve ast is identified by its standard designation in Specification E The alternative designation in parentheses is for information only and does not represent a different standard sieve size. This solution is the standard and requires no further standardization. Place the beaker on a magnetic stirrer and add a TFE-fluorocarbon coated stir bar. 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.
The exact normality shall be calculated from the average of three determinations as follows: NOTE 5—Slags and axtm cements contain sulfide sulfur in concentrations that can interfere with chloride determination unless oxidized with hydrogen peroxide. Directreading balances shall have a sensitivity not exceeding 0. 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.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Samples should be oven-dried and ground to pass a No. Some values have only SI units because the inch-pound equivalents are not used in asstm. To adtm sample contamination, avoid contact of sample with hands and other sources of perspiration. These notes and footnotes shall not be considered as requirements of this standard.

NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. Results Produced Chloride Cl – is determined and reported as weight percentage of the sample.
NOTE 7—It is not c112 to clean all the slurry residue from the sides of the beaker, nor is it necessary that the filter aatm all the fine material.
A slurry that is only slightly acidic is sufficient. Clean all sampling tools prior to each sampling operation See Note 4. Originally approved in Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample.
Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete. Rinse the beaker and the filter paper twice with small portions of water. Parte 1 de 2 Designation: The cooling water from core cutting may dissolve some of the chloride. Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C Such chloride will be detected by the use of this method.
Disperse the sample with 75 mL of water.
Link to Active This link will always route to the current Active version of the standard. If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0. F1152 Number Code Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure.
