Lightweight Concrete
Lightweight concretes can be produced with an overdry 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 to 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 – W/mK.
