Feb 01, 2012 1. Introduction. Lightweight concrete (LWC) has been widely used in buildings as masonry blocks, wall panels, roof decks and precast concrete units .Lightweight concretes can be produced with an oven dry density range of approximately 300–2000 kg/m 3, with corresponding cube compressive strengths from approximately 1 to over 60 MPa and thermal conductivities of 0.2–1.0 …
[email protected]Boral has specially designed Lightweight Concrete using a non-toxic treated polystyrene aggregate or by the use of cellular foam injection by specially trained applicators. Depending on local availability, special lightweight aggregates may also be included in the design for enhanced strength capability. Standard concrete as a density of around 2300kg/m3 and Lightweight concrete generally has ...

These are the Granite natural aggregate, the Dacite natural aggregate (an igneous volcanic rock with a high iron content and commonly used in Australia in concrete works), and another commercially available pelletized fly ash lightweight aggregate which will be referred to here as SP …

read moreJun 02, 2016 Lightweight concrete may weigh from 35 to 115 pounds per cubic foot, depending on the type of lightweight aggregate used or the method of production. In Bureau construction, lightweight concretes have been limited to those whose lightness depends on inorganic aggregates which are light in weight. 143. Types of Lightweight Aggregate.
read moreA: (Kelly) Lightweight concrete does not necessarily require the use of expensive or unusual additives. It is basically concrete that has replaced the standard heavy gravel aggregate with a lightweight substitute, such as crushed volcanic stone, perlite or vermiculite.
