Proportioning and characterization of lightweight concrete ...

Oct 01, 2008  The thermal conductivity of the lightweight concrete mixtures in the hardened state ranges between 0.22 and 0.67 W/m K for the dry specimens and between 0.60 and 1.33 W/m K for the specimens cured under water. The density of these mixtures is 25–63% lower as compared to that of the reference mixtures (without PUR-foam aggregates).

Proportioning and characterization of lightweight concrete ...

This paper presents the results of an experimental study concerning the incorporation of polyurethane (PUR) foam wastes into cementitious mixtures in order to produce lightweight concrete. A semi-empirical method is first proposed to predict the density of fresh PUR foam-based concrete mixtures. Seven concrete mixtures containing various PUR foam volume fractions (from 13.1% to 33.7%), and two ...

What is Lightweight Concrete? -Types, Uses and Advantages ...

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
