Ferro-cement is ideal in salt water - the effect of osmosis is to help pull the water OUT of the cement, which cures it. This process continues FOREVER as the cement gains in strength, though it becomes immeasurable after a number of years.

Yup. I've got compressive strength for cores for many years of the Powell River Hulks. Keeps getting stronger and stronger.
Chloride intrusion wise, some hulks actually do much better than the ACI 100 recommendations for modern concrete construction. Lots of engineers and scientists scratching their heads on that one. They figure it has something to do with the paste matrix from the materials the used to construct.
