Polymer-Impregnated Concrete Spherical Hulls under Hydrostatic Loading
Eight spherical models with outside diameters of 16 inches and wall thicknesses of 1 or 2 inches were fabricated of polymer-impregnated concrete (PIC) having a uniaxial compressive strength of 21,000 psi. The spherical specimens were tested under hydrostatic loading conditions of short-term, long-term, and cyclic pressure. The test results show that the PIC spheres respond to hydrostatic loading with linearly elastic behavior and that the implosion pressures are greater by approximately 40% than those for similar regular-concrete spheres. Under short-term loading the specimens having a wall-thickness-to-outside-diameter ratio of 0.063 and 0.125 (1- or 2-inch walls to 16-inch OD) implode at average hydrostatic pressures of 4,810 and 8,475 psi, respectively. Classical elastic theory predicts the strain behavior and implosion pressures of the PIC sphere within engineering accuracy. (Author)
