There are three different lightweight concrete type divisions in terms of strength range, which are low-density concretes (0.7–2.0 MPa), moderate-strength concretes (7–14 MPa) and structural concretes (17–63 MPa). The density of these concretes is in the range of 300–800 kg/m 3, 800–1350 kg/m 3 and 1350–≈1920 kg/m 3 respectively.
