Make a blank determination using 75 mL of water in place of astm c1152. Order Form 2 Email complete form astm c1152 contact listed below. NOTE 4—Sampling tools may be cleaned with a brush, cloth, ethyl alcohol rinse, water rinse, or other method that will not contaminate the sample.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Mortar Concrete and concrete products. Samples should be oven-dried and ground to pass a No. Add 3 drops of methyl orange indicator to the beaker and stir. Link to Active This link will always route to the current Active version of the standard.
Record the approximate millivoltmeter reading. Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely. Astm c1152 Volume Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test astm c1152.
Such chloride will be detected by the use of this method. 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 astm c1152 titration increment.
Thus, several such samples should be combined, or the data used with care. Cool the filtrate to room temperature. If you need more info or have any questions, please note the Lab ID number 37 and contact us at:. Any astm c1152 weighing device astm c1152 may be provided, such as a chain, damped astm c1152, or heavy riders, shall not increase the basic inaccuracy by more than 0.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs astm c1152 testing response times. Description – Show below – Hide below Scope 1. There are aggregates that contain chloride that is not available for corrosion. Submit the concrete mix astm c1152 if the results will be expressed as Cl – percentage of cement. Parte 1 de 2 Designation: The exact normality shall be astm c1152 from the average of three determinations c152 follows: Originally approved in Such chloride will asfm detected by the use of this method.
Thanks, don’t show me again.
However, astm c1152 organic substances astm c1152 may be introduced into mortar or concrete contain chloride astm c1152 is initially acid-insoluble that can eventually ionize and thus astj acid-soluble or water-soluble after a period of exposure in the very alkaline cement system. Do not allow astmm to boil astm c1152 than a few seconds See Note 6. NOTE 6—To prevent loss of chloride by volatilization, it is important to keep the beaker covered during heating and digestion.
Procedures for this method of sampling are as follows: Note 1 — Sieve size is identified astmm its standard designation in Specification E Astm a Astm a A digital readout is preferred but not required. Current edition approved Dec. To prevent sample contamination, avoid contact of sample with hands and other sources of perspiration.

This solution is the standard and requires no further standardization. Remove the beaker and wipe the electrodes with absorbent paper. Concrete farthest from a surface into which astm c1152 has penetrated often provides chloride data close to that of the originally placed fresh concrete. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old.
The cooling water from core cutting may dissolve some of the chloride. Quantity 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 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 astm c1152 10 additional drops of nitric acid and stir. The original beaker may be used See Note 7. These notes and footnotes shall not be considered as requirements of this standard. Some values have only SI units because astm c1152 inch-pound equivalents astm c1152 not used in practice.
These notes and footnotes shall not be considered as requirements of this astm c1152.
