Yearly Inspection of Concrete Test Specimens at Treat Island Containing Fly Ash, Silica Fumes and Slag for the Department of Energy, Mines and Resources

摘要

In view of the limited number of years that the concrete test specimens have been at the exposure site it would appear prudent to wait a little longer before making specific recommendations. The variables investigated are such that deterioration is on the threshold of proceeding rapidly and to obtain maximum information the specimens should be examined and studied closely over the next decade. During that time the effect of mix proportion, cement type and the role of supplementary cementing materials should become evident. It is of prime importance to maintain adequate labeling and documentation of the specimens at the site so that should a storm disrupt the installation the specimens can be identified and repositioned. 1 figures, 4 tables.
