Abstract: The US Army Corps of Engineers initiated in 1984 a research program designated Repair, Evaluation, Maintenance, and Rehabilitation (REMR), one of the work units being the evaluation of surface treatments to minimize concrete deterioration. Many Corps hydraulic structures have experienced concrete surface deterioration due to freezing and thawing, aggressive chemical exposure, and erosion, and Corps personnel surveys show freezing and thawing as the major contributing factor, closely followed by erosion. Different types of surface treatments evaluated under this work unit included concrete sealers, coatings, polymer systems, thin overlays, and shotcrete.
