Sand from a beach is contaminated with all sorts of chemicals that will cause severe deleterious reactions to a concrete paste. If we are speaking of sand from an ocean environment the salt [Chloride] content is around 4%.
Chlorides commence corrosion cell formation on embedded steel reinforcement in a matter of hours. With corrosion comes rust which expands the volume area of the steel. As the steel corrodes and expands the expansion causes a concrete to crack. When a crack becomes larger it allows even more chlorides moisture and oxygen free access to the steel which corrodes even faster. A design using beach sand is a prescription for concrete failure.
Attempts at washing a beach sand are futile. Structures built with beach sand are doomed from the day they are poured
