Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Instructions Supply 5 kg sample. Historical Version s – view previous versions of standard.

Within the text, the inch-pound units are shown in brackets. Can extend time of testing for additional charge. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest.
Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. Further discussion of these and other technical issues is given in the Appendix. Significance and Use 3.

Mix the solution on the day before use, cover, and store at 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.
Seal astn container with a lid so that the sulfate solution cannot evaporate.
Originally approved in 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 length change of mortar bars immersed in sulfate solution is the indicator.
Order Form 2 Email complete form to contact listed below. Reagents and Materials 5. A number in parentheses indicates the year of last reapproval. Further discussion of these and other technical issues is given in the Appendix.
Use This test provides a means of assessing the sulfate resistance of a mortar. Determine the pH of the solution before use; reject the solution if the pH range is outside 6.
Use a water-cement ratio by mass of 0. 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.

Support the bars so that no end or side of a bar rests against the container. Current edition approved Jan. Combining values from the two systems may result in non-conformance with the standard.
Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Last previous edition approved in as C — Work Item s – proposed revisions of this standard. 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 asm the specified sulfate concen- tration.
