Effects of sea water on concrete
WebJan 1, 1995 · As part of a durability study, this paper describes the mixing and curing effect of sea water on setting time, compressive strength of cement-sand mortar and corresponding concrete, rebar corrosion, chloride content and variation of alkalinity over a period of 18 months in a laboratory simulated splash/tidal zone of marine environment. WebA breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass (e.g. with caissons), or by using a revetment slope (e.g. with rock or concrete armour units). In coastal engineering, a revetment is a land-backed structure whilst a breakwater is a sea-backed structure (i.e. water on both sides).
