Abstract: A pregrouted PC steel material (10) includes a 19-wire-twisted PC strand (1), a pregrouted layer (2) disposed on an outer periphery of the PC strand (1), and a sheath (3) configured to cover an outer periphery of the pregrouted layer (2). A filling resin (4) is filled between steel wires (side wires) (1b, 1c, 1d). Since the filling resin (4) does not exude to the pregrouted layer (2) before tensioning of the PC strand (10), an operation of tensioning the PC strand (1) is not hindered by curing of the pregrouted layer (2). In contrast, since the gap between the steel wires is reduced when the PC strand (1) is tensioned, the filling resin (4) flows out (exudes) from between the steel wires to the pregrouted layer (2) to cure the pregrouted layer (2) only after the reduction.
