Standards Development
This document describes test methods (reference and alternative) applicable to cast test specimens for evaluating the Sulftate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks.
In these methods, the test is carried out under controlled exposure conditions using an increased concentration of sulfate solution. These test conditions are intended to accelerate external sulfate attack.
The reference test method is adapted from the modified SVA test method (German Institute for Building Technology (DIBt), Expert Committee (SVA)): “Testing the Sulfate Resistance of Cements with pozzolanic main constituents”. The modified SVA test method is listed in European Assessment Document – EAD 150007‑01‑0301, Annex C. This test method is appropriate for various binders, in particular those with pozzolanic main constituents.
The alternative test method is listed in European Assessment Document – EAD 150009‑01‑0301, Annex A. This test method is appropriate for CEM III/A cements.
