ASTM C Hydraulic-Cement Mortars Exposed to a Sulfate | CTLGroup
Test Method C is suitable for evaluating portland cements but not blended aztm or blends of portland cement with pozzolans or slags.
Reagents and Materials 5. Within the text, the inch-pound units are shown in brackets. Support the bars so that no end or side of a bar rests against the container.
Significance and Use 3. 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.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Portland cements may be evaluated asstm ASTM Chowever C c012 not suitable for evaluating blended cements or blends of supplementary cementitious materials with ordinary portland cement.
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.
Combining values from the two systems may result in non-conformance with the standard. Maintain the volume proportion of sulfate solution to mortar aatm in a storage container at 4. Work Item s – proposed revisions of this standard.
Instructions Supply 5 kg sample. If you need more info or have any questions, please note the Lab ID number and contact us at:.
Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. Originally approved in Further discussion of these and other technical issues is given in the Appendix. Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest.
Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. The length change of mortar bars immersed in sulfate solution is the indicator. Mix the solution on the day before use, cover, and store at 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.
Print and complete the following order form. Use This test provides a means of assessing the sulfate resistance of a mortar. Such chemicals shall conform to the specifica- tions of c012 Committee on Analytical Reagents for the American Chemical Society where such specifications are available.

Further discussion of these and other technical issues is given in the Appendix. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. A number in parentheses indicates the year of last reapproval. Seal the container with a lid so that the sulfate solution cannot evaporate. The values shown in parentheses are for information purposes only.
Results Produced Length change of mortar bars immersed in sulfate solution. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Can extend time of testing for additional charge.
Testing goes to 1 year. Last previous edition approved in as C — Order Form 2 Email complete form to contact c1021 below. Determine the pH of the solution before use; reject the solution if the pH range is outside 6.
