Static uniaxial tensile tests and water leakage tests were carried out on two types of ferrocement plates; type A and type B specimens were defined by DnV “Tentative rules for the construction and classification of ferrocement vessels”. Type A specimen consists of 4 to 12 layers of the same type of netting. Type B specimen consists of one layer of reinforcing rods and 6 or 12 total layers of netting. The main reinforcing netting used in specimen was a woven wire cloth with mesh width of 8 and 10 mm. Two series of experiments using equal contents of the mortar were tested. The tensile strength and the displacement behaviors of ferrocement plates due to tensile load, such as elastic modulus, Poisson's ratio, and elongation, were discussed in connection with the volume fraction and the specific surface of reinforcement. Leakage behaviors were studied from the viewpoints of the crack width and the ratio of applied stresses to the ultimate tensile stress of a ferrocement plate. Basic data for design were obtained in this study.
