Sea salt is a lot more than sodium chloride, the sulfates and many other things will attack the portland cement itself. The sand can be washed in fresh water, and test cylinders made. Unless you are going to make a lot of concrete, it'll probably be safer, cheaper and easier to buy sand from the supplier of the remaining aggregate.
