Lightweight Concrete Info...

A lightweight concrete is one which simply weighs less than a similar volume of 'standard' concrete.  If a standard concrete weighs about 150 pounds per cubic foot, the same volume of a lightweight concrete may weigh in the range of 90-120 pounds.

Lightweight concrete can be produced using various lightweight aggregates.

Lightweight aggregates originate from either:

bulletNatural materials such as volcanic pumice
bulletThermal treatment of clay, slate or shale
bulletManufacture from industrial by-products such as fly ash
bulletProcessing of industrial by-products such as slag
 
Lightweight concretes can many times be used in the same manner as conventional concretes and obtain strengths consistent with conventional concrete.

Benefits of using lightweight concretes include:

bulletReduction in dead loads placed on structure by concrete
bulletImproved thermal properties
bulletImproved fire resistance
bulletReduction of formwork and bracing due to lower weight
