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. Determine the pH of the solution before use; reject the solution if the pH range is outside 6.
The length change of mortar bars immersed in sulfate solution is the indicator. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available.

BoxFarmington Hills, MI Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest.
For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Originally approved in If you need more info or have any questions, please note the Lab ID number and contact us at:.
Results Produced Length change of mortar bars immersed in sulfate solution. Maintain the volume proportion of c10122 solution to mortar bars in a storage container at 4. Support the bars so that c10012 end or side of a bar rests against the container.
Can extend time of testing for additional charge. Use a water-cement ratio by mass of 0. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. Testing goes to 1 year.
