Sea Sand for Construction[Reality and Truth] Structural
Sea sand contains chloride ions beyond the acceptable limit causes sever durability issues. Therefore, much attention is required when offshore sand is used in construction. The chloride content in the concrete is limited to 0.4% by mass of cement generally. BS 5328 Part 1 1997 specify this limit and BS 882 1992 have bit higher values (0.5%).

Admixtures and additives for concrete PCC Group
Admixtures of this type enable mixing of air bubbles into the concrete mass and spreading them evenly throughout its volume. With this modification, the concrete becomes frost-resistant and less absorbent, but its compressive strength decreases. The addition of 1% air to the concrete mass means a decrease in strength by about 5Mpa.
