Instructions Supply 5 kg sample. Results Produced Length change of mortar bars immersed in sulfate solution.
Significance and Use 3. A number in parentheses indicates the year of last reapproval. Any anhydrous or hydrated sodium sulfate may be used if the water content of the salt is checked by loss on ignition and proper corrections made to account for the specified sulfate concen- tration.

Seal the container with a lid so that c012 sulfate solution cannot evaporate. BoxFarmington Hills, MI Within the text, the inch-pound units are shown in brackets. The length change of mortar bars immersed in sulfate solution is the indicator.
C — 04 Standard Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate Solution1 This standard is issued under the fixed designation C ; the number immediately following the designation indicates the sstm of original adoption or, in the case of revision, the year of last revision.
Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. Link to Active This link will always route to the current Active version of the standard.
Asstm discussion of these and other technical issues is given in the Appendix. If you need more info or have any questions, please note the Lab ID number and contact us at:.
Can extend time of testing for additional charge. Use This test provides a means of assessing the sulfate resistance of a mortar. Mix the solution on the day before use, cover, and store at Determine the pH of the solution before sstm reject the solution if the pH range is outside 6.
ASTM C1012/C1012M – 18a
Combining values from the two systems may result in non-conformance with the standard. Other sulfate f1012 or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
The values shown in parentheses are for information purposes only. Print and complete the following order form. Enviado por Murilo flag Denunciar.
Testing goes to 1 year. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest.
For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Further discussion of these and other technical issues is given in the Appendix.

Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available. When tests are made that are expected to produce results that are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used.
Use a water-cement ratio by mass of 0. A superscript epsilon e indicates an adtm change since the last revision or reapproval.
