    FLEXURAL HYBRID SPAN BEAM

    A method for producing a flexural hybrid span beam includes casting a first layer of ultra-high performance concrete (UIHPC) into a bottom of a mold, the first layer comprising steel fibers that are randomly oriented and dispersed. The method includes self-curing the first layer for at least 48 hours to form an unfinished top surface of the first layer. The method includes casting a second layer of plain concrete, over the unfinished top surface of the first layer, in the mold, wherein the second layer of plain concrete is not reinforced by steel bars. The method includes curing the first layer and the second layer to form the flexural hybrid span beam. An interface between the first layer and the second layer is substantially flat and has a periphery conforming to a shape of the mold.
