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

Density of Concrete
Air-entrained concrete is good in harsh weather and is used for roads and airport runways. High-early-strength Concrete is used in hurried jobs and cold weather because it hardens quicker than ordinary concrete. Lightweight concrete weighs less than any other concrete because it is made from pumice: a naturally light mineral. Katrina Jones -- 1999

Aggregate in Concrete
Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.

A novel lightweight concrete-fabrication and its thermal and
Lightweight concrete can be obtained by introducing gas or foam into the concrete paste, or by totally or partially replacing standard aggregate with low weight and preferentially low cost components. Foam concrete has been widely used in non-structural applications , , , . In general, lightweight aggregates are broadly classified into two types: natural (e.g., pumice, diatomite, volcanic cinder) and artificial (e.g., perlite, clay, sintered fly ash, expanded shale).
