The exact normality shall be calculated from the average of three determinations as follows: Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
A number in parentheses indicates the year of last reapproval. Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in.

Link ast, Active This link will always route to the current Active version of the standard.
Ten seconds of boiling is sufficient. Some values have only SI units because the inch-pound equivalents are not used in practice. Astm a Astm a Make a blank determination using 75 mL of water in place of sample.
ASTM Volume Conventional two-pan balances shall have a maximum sensibility reciprocal of 0. No lubricants shall be used during drilling. CM or as required for the purpose of the investigation. Results Produced Chloride D1152 – is determined and reported as weight percentage of the sample. Disperse the sample with 75 mL of water.
Thus, several such samples should be combined, or the data used with care. Do not allow sample to boil more than a few seconds See Note 6. Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure.
Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete. A digital readout is preferred but not required.
Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample. Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference.
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 prior to use. Samples should be oven-dried and ground to pass a No. NOTE 5—Slags and slag cements contain sulfide sulfur in concentrations that can interfere with chloride determination unless oxidized with hydrogen peroxide.
Rinse the beaker and the filter paper twice with small portions of water.
No further reproductions authorized. Originally approved in Some values have only SI units because the inch-pound equivalents are not used in practice.
If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. To prevent sample contamination, avoid contact of sample with hands and other sources of perspiration. If you need more info or have any questions, please note the Lab ID number 37 and contact us at: Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely.
The volume should not exceed mL. For testing to meet water soluble specification limits, tests should be performed on samples at asmt 28 days old. Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C In most cases, acid-soluble chloride is equivalent to total chloride.

C11522, 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.
Print and complete the following order form. Heat the covered beaker rapidly to boiling and remove from hot plate. 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. Dissolve in water and dilute to exactly 1 L in a volumetric flask and mix thoroughly. Dilute to 1 L in a volumetric flask and mix thoroughly.
NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies astj with temperature at low concentrations. A slurry that is only slightly acidic is sufficient. Cool the filtrate to room temperature.
