Use This zstm provides a means of assessing the sulfate resistance of a mortar. Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3.
ASTM C1012/C1012M – 18a
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Further discussion of these and other technical issues is given in the Appendix. Maintain the volume proportion cc1012 sulfate solution to mortar bars in a storage container at 4. 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.
Reagents and Materials 5. When tests are made that are expected to produce results v1012 are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used. Combining values from the two systems may result in non-conformance with the standard.

If you need more info or have any questions, please note the Lab ID number and contact us at:. Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Results Produced Length change of mortar bars immersed in sulfate solution.
Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Use a water-cement ratio by mass of 0. Significance and Use 3. The values shown in parentheses are for information purposes only.
Testing goes to 1 year. Link to Active This link will always route to the current Active version of the standard.
Within the text, the inch-pound units are shown in brackets. Print and complete the following order form. 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.
Other sulfate concentrations or other sulfates such as MgSO4 may be used to x1012 the environmental exposure of interest.
Determine the pH of the solution before use; reject the solution if the pH range is outside 6. 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. Seal the container ast a lid so that the sulfate solution cannot evaporate. 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.
