The present paper investigates experimental mechanical properties of lightweight concrete mixes produced with expanded glass aggregate. Different concrete mixtures (totally 12) from normal weight to extremely lightweight structural concrete have been made. The sand by its volume was replaced with the expanded glass. All specimens were tasted after 7 and 28 days of hardening to identify flexural and compressive strength. Density of concrete mixes ranged from 1458 to 2347 kg/m3, and the compressive strength of 40×40×40 mm cubes ranged from 40 to 103 MPa. As a result, strength and density relationship of lightweight concrete was obtained. The performed experimental investigations on freezethaw resistance and alkaline corrosion have shown good durability of the designed mixes.
