Polymer impregnated concrete and polymer concrete overlays

Abstract

The feasibility of impregnating bridge decks with methylmethacrylate for protection against freeze-thaw deteriorization and corrosion of the reinforcing steel is reported. Parameters such as monomer system, monomer loading, drying temperature and time, curing temperature and time, soak time and equipment were investigated and dicussed. A nondestructive method for the determination of the polymer depth in a polymer impregnated concrete was investigated and reported. The three methods that are presently used to place polymer concrete overlay on bridge decks were tested and compared with each other.
