Offshore sand is a capable alternative replacement for land aggregate in concrete. It isudnecessity for some country or regional where land aggregate is scarce and sometimes unavailable toudbe used for development but offshore sand is accessible for replacement. This paper reports about theudproduction and usage of synthetic lightweight coarse aggregate produced using offshore sandud(SYLCAG). It was produced with density of 1300 kg/m3ud which is nearly 60% lighter than normaludaggregate. This SYLCAG was used as a full replacement for coarse aggregate in concrete which thenudproduced as a concrete with density almost 1900 kg/m3. The produced concrete did not have a goodudstrength with design of 25 MPa concrete. However, it still has the potential to be develop with higheruddesign and later used as structural concrete
