Concrete in Marine Environments - Concrete Construction
One, proper mix proportions using the optimum cement content will yield a dense, impervious and relatively unabsorbent concrete. Two, the optimum concrete is 6 and one half to 7 and one half sacks per cubic yard and the water/cement ratio should not exceed 6 gallons per sack of cement to produce a mix that is plastic and workable.
