It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Further discussion of these and aastm technical issues is given in the Appendix. Combining values from the two systems may result in non-conformance with the standard. Originally approved in If you need more info or have any questions, please note the Lab ID number and contact us at: Link to Active This link will always route to the current Active version of the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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. Sample Type portland cement, blended cements, and supplementary cementing materials blended with portland cement.
Use a water-cement ratio by mass of 0. The length change of mortar bars immersed in sulfate solution is the indicator. 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.
A number in parentheses indicates the year of last reapproval. Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. If you need more info or have any questions, please note the Lab ID number and contact us at:.
Determine the pH of the solution before use; reject the solution if the pH range is outside 6. Further discussion of these and other technical issues is given in the Appendix.
ASTM C Hydraulic-Cement Mortars Exposed to a Sulfate | CTLGroup
Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. Testing goes to 1 year. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Enviado por Murilo flag Denunciar.

Significance and Use 3. Any anhydrous or asmt 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. Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags.
Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Support the bars so that no end or side of a bar rests against the container. Historical Version s – view previous versions of standard.
