Abstract:
Ferrocement has attracted world-wide interest because of its proven suitability for marine structures as well as its potential as a repair material. The first part of the paper describes methodology for accelerated exposure of specimens to the marine environment simulated in the laboratory. The main features of this methodology were: the cyclic temperature and moisture environment, and the preloading of specimens up to the state of cracking before placing them in this environment. The second part reports and discussed the influence of the duration of load and the cyclic environment on the fatigue properties measured from tests performed under cyclic loading. These properties are compared with those of the specimens stored in a normal curing room. Fatigue results obtained from the ferrocement specimens are compared with those from the reinforcing wires tested in the air. The fatigue performance of reinforcement in the air was found to be considerably lower than that in the composite.
