Investigation of Deterioration of Brick in Navigation Lock Control House Structures, Tulsa District.

Abstract

The deterioration of brick in certain control house structures at five navigation locks was characterized by partial or complete separation of laminations from the face of several bricks. Some of the laminations had fallen completely off. Deteriorated and nondeteriorated samples were removed from several structures and were evaluated by physical testing and petrographic examination. The deterioration mechanism was identified as moisture intrusion accompanied by freezing and thawing. Six model walls were constructed and each was coated with a different protective coating to determine the effectiveness of such treatment. The six coatings were rated in order of efficiency in producing protection with urethane coatings outperforming epoxy and silicone coatings. (Author)
