Coatings and Sealers to Treat Concrete Deterioration
Which physical properties of concrete sealers and coatings are the most relevant for predicting in-servive performance?
Need and Benefit
Cracking in concrete is widely regarded as a long-term durability and maintenance problem. Cracks can allow ingress of moisture and and other compounds into concrete leading to further deterioration. Cracking is a problem that occurs in most geographical locations and climates, and in many types of concrete structures.
Reclamation has a large inventory of aging concrete that is experienceing deterioration. Effective sealing and coating compounds could slow or halt deterioration in some cases. In addition, there is very little known about which sealing and coating properties are the most relevent to review when choosing a product. Being able to select products that are the most likley to work based on their published material properties will help ensure that repairs are made as effectively as possible.
