Seawater Absorption and Compressive Strength of Concrete at Ocean Depths
The results of two limited investigations on seawater absorption and compressive strength of 6 x 12-inch concrete control cylinders subjected to ocean environmental conditions are given. Seawater absorption of field-dry concrete was found to be 2.36% by weight after exposure to a pressure head to 550 feet for 84 days. Uniaxial compressive strength of concrete saturated and tested under a pressure head of 20,000 feet decreased by 10% when compared to the compressive strength of fog-cured concrete. Concrete under 1-foot and 500-foot pressure heads had a strength similar to that of fog-cured concrete. Seawater abosrption is an important design consideration for massive, floating concrete structures because near-neutrally buoyant conditions are required for the structures at various stages of construction, installation, or operation.
