A number in parentheses indicates the year of last reapproval. If you need more info or have any questions, please note the Lab ID number and contact us at:. Sample Type portland cement, blended cements, and supplementary cementing materials blended with portland cement. Testing goes to 1 year.
BoxFarmington Hills, MI Referenced Documents purchase separately Ashm documents listed below are referenced within the subject standard but are not provided as part of the standard. When tests are c1021 that are expected to produce results that are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used.
Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. Results Produced Length change of mortar bars immersed in sulfate solution. Further discussion of these and other technical issues is given in the Appendix.

For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Support the bars so that no end or side of a bar rests against the container. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.
The values shown in parentheses are for information purposes only. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Can extend time of testing for additional charge. Originally approved in Order Form 2 Email complete form to contact listed below.
Print and complete the following order form. 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. Enviado por Murilo flag Denunciar.

Mix the solution on the day before use, cover, and store at Current edition approved Jan. Work Item s – proposed revisions of this standard. Further discussion of these and other technical issues is given in the Appendix. 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 year of original adoption or, in the case of revision, the year of last revision.
Time for Results Please contact a Asgm chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Use a water-cement ratio by mass of 0.
Combining values from the two systems may result in non-conformance with the standard. Within the text, the inch-pound units are shown in brackets. If you need more info or have any questions, please note the Lab ID number and contact us at: Seal the container with a lid so that the sulfate solution cannot evaporate.

Reagents and Materials 5.
Instructions Supply 5 kg sample. Significance and Use x1012. Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available.
Portland cements may be evaluated by ASTM Chowever C is not suitable for evaluating blended cements or blends of supplementary cementitious materials with ordinary portland cement. Link to Active This link will always route to the current Active version of the standard.
Determine the pH of the solution before use; reject the solution if the pH range is outside 6. Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
