The content of impurities in sea sand was measured in accordance with JGJ206-2010. The silt, sulfide, and light component contents of sea sand are similar to those of river sand, whereas the chloride and shell contents of sea sand are much higher than those of river sand. The gradation of sea sand particles was measured in ac-
