Hybrid fiber reinforced cementitious material

Abstract

There is provided a cementitious mixture and method of making same. The cementitious mixture includes a cementitious material, aggregate and water. The cementitious mixture further includes a combination of fiber reinforcement, which includes a first amount of polymeric material fiber and a second amount of recycled polymeric fiber. According to embodiments, a relationship between the first amount of fiber and the second amount of fiber is defined by a ratio, wherein the ratio is between 1:7 and 7:1. The ratio of 1:7 is indicative of the total fiber in the cementitious mixture being 12.5% polymeric material fiber and 87.5% recycled polymeric fiber (RPF) and the ratio 7:1 is indicative of the total fiber in the cementitious mixture being 87.5% polymeric material fiber and 12.5% RPF fiber.
