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. Page xstm John S. Chemical Society, Washington, DC. Dilute to 1 L in a volumetric flask and mix thoroughly. This solution is the standard and requires no further standardization.
Astm c astm normas fibra de vidrio. Cover the awtm with a watch glass and allow to stand for 1 to 2 minutes. Historical Version s – view c11152 versions of standard. A number in parentheses indicates the year of last reapproval. Rinse the beaker and the filter paper twice with small portions of water. 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 f1152 reapproval.
Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure. If you need more info or have any questions, please note the Lab ID number 37 and contact us at: Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results.
The alternative designation in parentheses is for information only and does not represent a different standard sieve size. The volume should not exceed mL. Disperse the sample with 75 mL of water. These notes and footnotes shall not be considered as requirements of this standard.
The cooling water from core cutting may dissolve some of the chloride. Concrete and Concrete Aggregatesand c11152 the direct responsibility of Subcommittee C Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample. Samples should be oven-dried and ground to pass a No. To prevent 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.
Ten seconds of boiling is sufficient.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Make a blank determination using 75 mL of water in place of sample.

Any rapid weighing device that may be provided, such as a chain, damped motion, or heavy riders, shall not increase ast basic inaccuracy by more than 0. Submit the concrete mix design if the results will be expressed as Cl – percentage of cement. Such chloride will be detected by the use of this method.
Heat the covered beaker rapidly to boiling and remove from hot plate.
