The Effect of Surface Coatings and Bonded Overlays on Moisture Migration.

摘要

Tests were made on concrete specimens that had been coated with four different waterproofing materials to determine how far the coatings penetrated into the concrete. Also,coated surfaces and overlaid specimens were ponded over with salt water and tap water to determine the effectiveness of each to prevent the migration of moisture into the concrete specimens. Freeze-thaw tests were made on asphaltic overlays to determine the effect of freeze-thaw cycling on the overlays and the portland cement concrete beneath the overlays. Shear tests were made to determine the shear strength of concrete overlays bonded to concrete test blocks. (Author)
