Lightweight Concrete - an overview ScienceDirect Topics

Lightweight concretes can be produced with an over-dry density range of approximately 300 to a maximum of 2000 kg/m 3, with corresponding cube strengths from approximately 1 to over 60 MPa and thermal conductivities of 0.2 to 1.0 W/mK. These values can be compared with those for normal weight concrete of approximately 2100–2500 kg/m 3, 15 to greater than 100. MPa and 1.6–1.9 W/mK.
