Materials Free Full-Text Sulfate Resistance in Cements
This study explores the effect on sulfate resistance of the use of ornamental granite industry waste as a supplementary cementitious material (at replacement ratios of 10 and 20 ) in cement manufacture. The present paucity of scientific knowledge of the behaviour of these new cements when exposed to an external source of sulfates justifies the need for and the originality of this research.

Test Methods for Resistance of Concrete to Sulfate Attack
Sep 20 2012 · Abstract. Sulfate attack comprises a series of chemical reactions between sulfate ions and the components of hardened concrete. As these reactions may lead to cracking spalling or strength loss of concrete structures appropriate test methods are needed to determine the resistance of concrete under sulfate exposure.
