Can extend time of testing for additional charge.
Other sulfate concentrations or other sulfates such as MgSO 4 may be used c10122 simulate the environmental exposure of interest. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Historical Version s – view previous versions of standard. Further discussion of these and other technical issues is given in the Appendix.
Use a water-cement ratio by mass of 0. Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Reagents and Materials 5. Within the text, atm inch-pound units are shown in brackets. Sample Type portland cement, blended cements, and supplementary cementing materials blended with portland cement. Print and complete the c101 order form.
Seal the container with a lid so that the sulfate solution cannot evaporate. Link to Active This link will always route to the current Active version of the standard. Determine the pH of the solution before use; reject the solution if the pH range is outside 6. Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. 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. Order Form 2 Email complete form to asfm listed below.
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. Portland cements may be evaluated by ASTM Chowever C is not suitable for evaluating blended cements or blends of supplementary cementitious materials astmm ordinary portland cement. The length change of mortar bars immersed in sulfate solution is the indicator.
Enviado por Murilo flag Denunciar. Mix the solution on the day before use, cover, and store at Last previous edition approved in as C — Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Combining values from the two systems may result in non-conformance with the standard.

Support the bars so that no end or side of a bar rests against the container. Testing goes to 1 year. A number in parentheses indicates the year of last reapproval. Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available.
Originally approved in BoxFarmington Hills, MI Instructions Supply 5 kg sample. Current edition approved Jan.

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. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Use This test provides a means of assessing the sulfate resistance of a mortar. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Further discussion of these and other technical issues is given in the Appendix.
