Behavior of spherical concrete hulls under hydrostatic loading -- 1
Hollow concrete spheres 16 in. in OD were tested to destruction by exposure to external hydrostatic pressure in seawater to determine compressive strength and permeability of concrete under loading; testing showed that for particular mix used, compressive strength of dry concrete in spherical hull of 16-in. OD and 1-in. wall thickness under biaxial loading is approximately 48% higher than for identical dry concrete in 3-in.-diam by 6-in.-long solid test cylinders under axial loading conditions; permeability of uncoated spheres to seawater at simulated ocean pressure of 1500 psi was approximately 6×10-3 ml/hr/sq in. of area per 1 in. of thickness.
