1.1 This test method provides a means of assessing the sulfate resistance of hydraulic cement by measuring expansion after immersion in a sodium sulfate solution after curing for 7 days of small bars 10 mm x 10 mm x 60 mm.
The current test to determine the resistance of cement to sulfate attack (C1012) takes over a year to complete. This test would allow to obtain the same answer in just 3 months. This test is needed by the cement industry.
