Title: Effect of Carbon Black and Black Iron Oxide on Air Content and Durability of Concrete
Author(s): Thomas G. Taylor
Publication: Journal Proceedings
Appears on pages(s): 613-624
Abstract:The practice of using air-entraining cement and air-entraining admixtures has made it necessary to re-examine many of the materials added to concrete to determine their effect on these types of concrete. This paper reports tests made to determine the effect of certain coloring agents on the air content and durability of concrete. The tests indicate that some materials when added to concrete reduce the capacity of the cement to entrain air and thereby reduce the resistance of the concrete to freezing and thawing. A recommended procedure for evaluating coloring agents for use in air-entraining concrete is given.
