sea sand (2) to analyze the compressive strength of sea sand concrete with fresh water and
sea water curing. In this study, the specimens used were 21 cylinders with a job mix design
plan of f'c 25 MPa with a curing duration of 7 days, 14 days, and 28 days. At the age of 7 and
14 days the compressive strength of fresh water curing was 30.29 MPa and 33.12 MPa
higher than seawater curing 29.02 MPa and 32.13 MPa, while at 28 days the compressive …
