Materials Science of Concrete Sulfate Attack Mechanisms [Hardcover]

This volume contains ten invited presentations on the topic of sulfate attack caused by external sulfate sources. The discussions concentrate on chemical and physical mechanistic aspects of the applicable sulfate-to-paste reactions and on the interrelationships between the internal (e.g., paste composition, pore solution, concrete matrix permeability) and external (e.g., composition of aggressive medium, temperataure and humidity, curing practices) variables.Discussion of Presented Papers.
