Lightweight concrete is defined by both ASTM and EN standards as a type of concrete that has an in-place density of less than 2000 kg/m³ (125 lb/ft³). This unique property arises from the incorporation of lightweight aggregates, such as expanded clay which reduce the overall density without compromising strength.
Non-Structural:
700 kg/m³ at 3 MPa
1000 kg/m³ at 5 MPa
1200 kg/m³ at 15 MPa
Structural:
1400 kg/m³ at 25 MPa
1600 kg/m³ at 35 MPa
1800 kg/m³ at 45 MPa
This type adheres to specific performance criteria, maintaining adequate compressive strength while being significantly lighter than traditional concrete. Structural lightweight concrete is particularly beneficial where weight reduction is essential without sacrificing the integrity of the structure.

This variation is designed primarily for applications that do not require high strength but provide insulation, sound reduction, or filling. Non-structural lightweight concrete focuses on enhancing thermal and acoustic performance.
