Combining values from the two systems may result in non-conformance with the standard. Use This test provides a means of assessing the sulfate resistance of a mortar.
Originally approved in 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. Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4.

Last previous edition approved in as C — Mix the solution on the day before use, cover, and store at Testing goes to 1 year. For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container.
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. BoxFarmington Hills, MI The length change of mortar bars immersed in sulfate solution is the indicator. Further discussion of these and other technical issues is given in the Appendix.

ASTM C Hydraulic-Cement Mortars Exposed to a Sulfate | CTLGroup
Sample Type portland cement, blended cements, and supplementary cementing materials blended with portland cement.
Any anhydrous or hydrated sodium sulfate may f1012 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. Instructions Supply 5 kg sample. Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest.
Use a water-cement ratio by mass of 0. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the asmt. Can extend time of testing for additional charge. 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 c0112 to use.

Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. 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 CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Results Produced Length change of mortar bars immersed in sulfate solution. Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3.
Significance and Use 3. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags.
A number in parentheses indicates the year of last reapproval. The values shown in parentheses are for information purposes only.
