ACI SP-317:2017 PDF Download

ACI SP-317:2017 is a compilation of papers presented at a session sponsored by ACI Committee 201, Durability of Concrete. The papers address various aspects of sulfate attack on concrete, which is a complex process characterized by damage manifestations such as volumetric expansion, cracking, spalling, softening, and mushiness. Sulfate attack can be classified as internal or external to the cementitious matrix, with damage modes being chemical or physical. The papers cover theoretical and experimental aspects of different forms of sulfate attack and urge readers to critically evaluate the work presented in the context of existing knowledge and scientific literature on this durability topic. The topics covered in the papers include criteria for sulfate-resistant concrete mixtures, influence of binder composition on performance, damage characterization, alternative binders, durability of pre-placed aggregate concrete, strengthening of sulfate-damaged concrete, criteria for mixtures resistant to physical salt attack, ultrasonic pulse velocity testing for assessing sulfate-degraded concrete, effects of supplementary cementitious materials and exposure temperature, and sulfate resistance of mortar bars in different sulfates.
