Methods of testing cement - Part 16 - Sulfate resistance - Square prism method

Scope

This document describes a test method applicable to cast test specimens for evaluating the Sulfate
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 a defined concentration of sulfate solution. The chosen test conditions are
intended to accelerate external sulfate attack.
This test method is appropriate in particular for CEM III/A cements and other various binders, in
particular those with pozzolanic main constituents. It is adapted from the CUR - NL - Civieltechnisch
Centrum Uitvoering Research en Regelgeving (Centre for Civil Engineering Research and Codes) -
Recommendation 48 - Suitability test for new cements for application in concrete.
This test method is listed in European Assessment Document - EAD 150004-00-0301, Annex B.
