Title: A Case of Abnormally Slow Hardening Concrete for Tunnel Lining
Author(s): Lewis H. Tuthill, Robert F. Adams, Shelly N. Bailyey, and Ronald W. Smith
Publication: Journal Proceedings
Appears on pages(s): 1091-1110
Abstract:When job concrete does not set for several days there is usually a reason. When the correct reason is not found, the blame may fall where it is undeserved but worse still, nothing is learned to prevent a recurrence. This paper describes such an experience and the related testing which shows that one cause of belated hardening, when a lignin-base water-reducing admixture is used, is too little SO3 in the cement.
