The concrete consisting of a hard, chemically inert particulate substance known as an aggregate (usually made from different types of sand and gravel), that is bonded together by cement and water. Aggregate can produced from any materials such as mining sand, offshore sand, pumice, scoria and etc. Offshore sand is a one of alternative for river sand usage in concrete. In this study, the coarse aggregates will be replaced with the synthetic lightweight coarse aggregate using offshore sand (SYLCAG) in concrete. The SYLCAG was produced with density of 1600 kg/m 3 which are 66.67% from density of normal aggregate. LA abrasion and aggregate crushing value (ACV) to determine the strength of SLYCAG. Concrete that produced using SYLCAG were test to obtain the mechanical properties that includes compressive strength, flexural strength and water absorption test. The offshore sand have potential to be produced as SYLCAG because there is very less lightweight aggregate such as pumice, scoria, etc. available in Malaysia.
