Rethinking Bridge Deck Longevity and Maintenance with Portland Cement Polymer Concrete
This research was directed at developing an alternative material for highway bridge decks and other construction applications typically achieved with ordinary Portland cement concrete. This alternative material is termed portland polymer concrete (PCPC) and differs from ordinary portland cement concrete through the inclusion if a polymer matrix intertwined with the Portland cement binding matrix. The polymer matrix is formed through the inclusion of a monomer during the mixing process which subsequently polymerizes throughout the cement matrix. This study was directed at reproducing PCPC with similar properties gains as achieved in 1980 noted by high tensile strength and a relatively high water impermability. Combined, these properties, result in lighter weight, crack resistant and highly durable concrete products. While these properties were not fully achieved in this study, it is believed the underlying mechanism to achieve these properties was discovered. Furthermore, using properties achieved in 1980, this study demonstrated life cycle costs could decrease by nearly 80 percent driven by large decreases in maintenance costs. Further material research is needed to optimize the mechanism associated with the polymer reinforcing matrix and achieve the properties observed in 1980.
