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.

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.

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.
