Results Produced Length change of mortar bars immersed in sulfate solution. Further discussion of these and other technical issues is given in the Appendix. 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.
Last previous edition approved in as C — The length change of v1012 bars immersed in sulfate solution is the indicator.
Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. Print and complete the following order form. Current edition approved Jan. Instructions Supply 5 kg sample.
Reagents and Materials 5. Support the bars so that no end or side of a bar rests against the container.
ASTM C1012/C1012M – 18a
Use This test provides a means of assessing the sulfate resistance of a mortar. Portland cements may be satm by ASTM Chowever C is not suitable for evaluating blended cements or blends of supplementary cementitious materials with ordinary portland cement.
The values stated in each system may not be wstm equivalents; therefore, each system shall be used independently of the other. If you need more info or have any questions, please note the Lab ID number and contact us at: A number in parentheses indicates the year of last reapproval.
Enviado por Murilo flag Denunciar. Work Item s – proposed revisions of this standard.
Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Historical Version s – view previous versions of standard.
The values shown in parentheses are for information purposes only. Originally approved in Testing goes to 1 year. Within the text, the inch-pound units are shown in brackets. Referenced Documents purchase separately The awtm listed below are referenced within the subject standard but are not provided as part of the standard.
Such chemicals shall conform to the specifica- tions of aztm Committee on Analytical Reagents for the American Chemical Society where such specifications are available. 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. Significance and Use 3.
Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest. 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. Combining values from the two systems may result in non-conformance with the standard. 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.
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. Can extend time of testing for additional charge.
