In this research two differences geometries of geopolymer lightweight concrete masonry units (GPLWCMUs) were produced. According to the Iraqi Standard No.1077/1987, the GPLWCMUs type I are classified as solid masonry units class A, that are used both in the interior and exterior walls which exposed to calamity effects. As concerned to GPLWCMUs type II, they are classified as hollow masonry units class B, which can be used in the constructions above ground level but not exposed to calamity effects. The density for the two types were 1575, 1350 kg/m 3 respectively, whereas water absorption and compressive strength for the two types ranged from 6-7.5%, and 13 MPa and 5 MPa. As a result: the two GPLWCMUs can be classified as lightweight units because they complain the Iraqi Standard No. 1129 for the year 1990.
