It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the astn bility of regulatory limitations prior to use. 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 sstm the year 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. Print and complete the following order form.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Instructions Supply 5 kg sample. Results Produced Length change of mortar bars immersed in sulfate solution. Use a water-cement ratio by mass of 0. For mortar bars 25 xstm 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. 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. Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest.
Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Seal the container with a lid so that the sulfate solution cannot evaporate. BoxFarmington Hills, MI Historical Version s – view previous versions of standard. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags.
Determine the pH of the solution before use; reject the solution if the pH range is outside 6. A number in parentheses indicates the year of last reapproval.

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 for the specified sulfate concen- tration.
