Specifies the procedure for determining the length change of mortar bars of defined composition immersed in a sodium sulfate solution. The length of change is taken as a measure of the sulfate resistance of portland and blended cement.

This Standard sets out the method for the determination of length change of mortar bars of defined composition immersed in a sodium sulfate solution. The length change is taken as a measure of the sulfate resistance of portland and blended cement.
