Title: Internal-Sulfate Attack in Portland Cement Products-the Role of Microcracks
Author(s): Yan Fu, Jian Ding and James J. Beaudoin
Publication: Special Publication
Appears on pages(s): 1433-1446
Keywords: Ettringite; microcracking; portland cement; sulfate attack.
Abstract:Results of an investigation of the deterioration of Portland cement products due to deleterious ettringite formation are described. The effects of thermal-drying on internal-sulfate attack in different concrete products is discussed. Comment on the relative significance of deterioration mechanisms is given. Delayed ettringite formation usually occurs in high-temperature cured products. It is usually associated with products exposed to conditions favorable to cracking (e.g. thermal-drying/re-wetting cycles).
