Abstract:
Methyl-methacrylate (MMA) based polymer concretes have been used for thin overlays, patching repairs, and bearing pad applications since the late 1970’s. These polymer concretes are moisture and wear resistive and have been used to protect embedded reinforcing steel from corrosion attack. This paper reports on the condition of a post-tensioned parking garage that was repaired in 1983 using a thin mma polymer concrete overlay. An earlier paper reported on the garage condition, repair methods and materials (1). Comments will be made on the overlay wear, cracking, bonding to the substrate, continued corrosion of embedded reinforcing steel, and surface delaminations after 13 years of service. Comparisons of conditions in 1981 and 1995 are also made. Comments on the success of the application with respect to structural integrity and material durability are made at the end of the paper.
