An evaluation of sealers based on eight sets of laboratory tests was done. Five concrete sealer treatments were studied: D335, DCS, SS, R7, and CT40. These sealers were evaluated for three groups of concrete mixes: normal, fly ash, and old concrete. There were also control specimens that did not use any type of sealer for comparison purposes. The test data were used to determine which sealer and concrete mix combination was the most adequate in improving resistance to the deterioration of concrete properties.
