Standard Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate Solution

Importancia y uso:

3.1 This test method provides a means of assessing the sulfate resistance of mortars made using portland cement, blends of portland cement with pozzolans or slags, and blended hydraulic cements. Test Method C452 is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags.

3.2 The standard exposure solution used in this test method, unless otherwise directed, contains 352 moles of Na₂SO₄ per m³(50 g/L). Other sulfate concentrations or other sulfates such as MgSO₄ may be used to simulate the environmental exposure of interest. Further discussion of these and other technical issues is given in the Appendix.
