The effects of steel and glass fiber addition on the compressive, tensile, and flexural strengths of methacrylate polymer concrete are presented. Tests were performed with fiber concentrations of one, two, and three percent by volume. The steel fibers resulted in significant improvement of all test strengths. The glass fibers decreased the compressive strength, but increased the tensile and flexural strengths. The effects of steel, glass, and nylon chopped fibers on shrinkage are also described. The fibers were added in varying amounts to two commercial methacrylate polymer concretes, and the drying or curing shrinkage was observed for the first 4 days. The different fibers were equally effective, with shrinkage reduction being proportional to the amount of fiber.
