摘要

Cylindrical ferrocement tanks were subjected to increasing internal water pressures to study the influence of the reinforcing parameters on their cracking and leakage behavior. Based on the information generated in this investigation,allowable tensile stresses of about 30,000psi in the steel are recommended for the design of virtually watertight ferrocement tanks. This allowable stress -which is almost twice higher than that recommended by the ACI Committee on reinforced concrete sanitary engineering structures -is used in a cost comparison study of water tanks made with ferrocement,reinforced concrete and steel. It is found that for current U.S. prices,properly dimensioned and designed ferrocement water tanks of up to 300,000gallon capacity are cost competitive with reinforced concrete and steel tanks and would have at least equal performance.
