Classification of Lightweight concrete: There are three broad classifications of lightweight concrete based on the method employed for production. 1. Lightweight Aggregate Concrete. In this method a porous lightweight aggregate of low Specific Gravity instead of normal aggregate of Specific Gravity is used. 2. Aerated, Cellular, Foamed or ...
Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.
Lightweight Aggregate Concrete Spectrum The concrete spectrum ensuing from the usage of the lightweight sum is highly diverse in nature runing from really lightweight sum concrete up to high strength sums dedicated for specific bespoke applications as argued by Glenn A. Black ( 2004 ) .
Utelite Lightweight Expanded Shale Aggregates. For over 50 years, Utelite Corporation has produced and supplied rotarykiln, high strength, structural lightweight expanded shale aggregates (ESLA). Expanded shale lightweight aggregates offer exceptional performance and value in .
The density of the resulting concrete will depend on the type of aggregate used. Lightweight aggregates may be used for the coarse aggregate in conjunction with natural fines, or lightweight can be used for both coarse and fine aggregates.
A concrete alternative (Australia) A new cementbased product that is half the weight of concrete yet provides five times more thermal insulation is about Latest industry news on Aggregates, Asphalt, Cement, Concrete and more.
Zonolite, when mixed with a Portland cement binder, in lieu of sand gravel aggregate and gravel aggregate, produces a lightweight insulating concrete. Weight per cubic foot is reduced from 140 lbs. to the 1837 pounds per cu bic foot range. Insulation values are increased 20 or more times those of structural concrete.
Description. This guide includes a definition of lightweightaggregate concrete for structural purposes and discusses, in a condensed fashion, the production methods for and inherent properties of structural lightweight aggregates. Current practices for proportioning, mixing, transporting, and placing; properties of hardened concrete;

Lightweight Concrete. Glass Mountain Lightweight Aggregate is currently supplying LiteRock™ lightweight concrete aggregate to the western United States from our mine and processing plant in Tulelake, California, approximately 60 miles southeast of Klamath Falls, Oregon, and our McClellan Park unloading center near Sacramento, California.
Lightweight concrete is primarily used to reduce the weight or load of a concrete structure, thus allowing for smaller sized columns and footings. Manufactured using lightweight aggregates, lightweight concrete can help in the construction of high rises and other buildings that require sturdy and safe flooring.
Lightweight Aggregate | Concrete Fabrication. Enhance cement flexibility, resilience, freezethaw durability, water repellency, and crack resistance with CityMix aggregate mix. CityMix substantially reduces overall weight – by up to 70% and, with 99% recycled waste by volume, bagged CityMix is the greenest concrete additive ever made.
The final product, lightweight synthetic aggregate, is a granular material to be used in construction industry for applications such as lig htweight fill, pre cast concrete elements, concrete structures, and insulation for utility pipelines.
Weight of Lightweight Aggregate Concrete. The weight of the lightweight aggregate concrete is around 115 pounds per cubic foot, whereas the weight of the normal weight concrete is 145 pounds per cubic foot. The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate.
Complete replacement of normal weight fine aggregate with a lightweight aggregate will decrease the concrete density by approximately 10 lb/ft3 (160 kg/m3). Designers recognize that structural lightweight concrete will not typically serve in an ovendry environment.
