Mix the solution on the day before use, cover, and store at Portland cements may be evaluated by ASTM Chowever C is not suitable for evaluating blended cements or blends of supplementary cementitious materials with ordinary portland cement.

Seal astn container with a lid so that the sulfate solution cannot evaporate.

Originally approved in 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.

The length change of mortar bars immersed in sulfate solution is the indicator.

Use This test provides a means of assessing the sulfate resistance of a mortar. Determine the pH of the solution before use; reject the solution if the pH range is outside 6.

Use a water-cement ratio by mass of 0. 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.
