ABSTRACT:
A filled structure characterized by the combination of high compressive and tensile strength to allow a high bending load includes a fiber reinforced resinous hollow structure having a tensile strength of at least 30,000 psi. The hollow structure has first and second ends, an inside surface forming a boundary which encloses a space, and an outside surface. At least a portion of the outside surface of one of the ends has a roughened portion sufficient to provide frictional resistance with the ground when the one end is driven into the ground. A hard core is disposed within the space enclosed by the hollow structure. The hard core has a density of at least 35 pounds per cubic foot and a compressive strength of at least 1500 psi. The hard core is formed from a mixture of particulate cementitious material and liquid.
