When tests are c1021 that are expected to produce results that are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used.

Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. Results Produced Length change of mortar bars immersed in sulfate solution. Further discussion of these and other technical issues is given in the Appendix.

For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Other sulfate concentrations or other sulfates such as MgSO 4 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. Support the bars so that no end or side of a bar rests against the container. 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.
