In July 1979, three 6- by 6- by 30-in. beams which had received surface impregnation of MMA were installed at half-tide elevation. These were portland cement concrete specimens of 1-year age. Two coated beams were installed in July 1981. The base concrete is the same as other specimens placed in 1978. The coating is a thin polymer. The polymer impregnated specimens are portland cement concrete (PCC) that was impregnated with MMA by vacuum and pressure soak. The program also includes control specimens of portland cement concrete with no treatment. The polymer concrete specimens represent two mixtures, one using methyl methacrylate (MMA), and one using vinyl ester (VE). | |
| In July 1978, twelve 6- by 6- by 30-in. beams were installed at half-tide elevation for the U.S. Bureau of Reclamation to investigate the durability and performance of polymer and polymer-impregnated concrete. | ||
