Considerable alarm was created about the year 1887 by the failure of two or three large structures of Portland cement concrete exposed to seawater, both in England and other countries.

On the other hand, if the concrete is rough and porous the sea-water will gradually eat into the heart of the structure, especially in a case like a dam, where the water, being higher on one side than the other, constantly forces its way through the rough material, and decomposes the Portland cement it contains.
