Classification and Advantages of Light Weight Concrete ...

The concrete whose density is lower than normal concrete (2200 kg/m 3 or 140 lb/ft 3) is known as lightweight concrete. It includes an expanding agent in it to increases the volume of the mixture while giving additional qualities.

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).

Pumce Concrete: Lightweight, Insulating, Durable

Lightweight aggregates are reactive, and if used with ordinary Portland cement without the mitigating effects of a reactive pozzolan, the concrete inevitably develops a nasty ASR problem—a reaction between the high silica content in the aggregate and the alkali in the hydrated cement paste. The alkali-silica reaction forms expansive gels that generate a sort of slow-motion explosion, map ...

CIP 36 - Structural Lightweight Concrete

2003 the range of 5% to 20% by weight of dry aggregate. Lightweight aggregates generally require wetting prior to use to achieve a high degree of saturation.

Understanding Different Types of Lightweight Concrete

For some lightweight concrete formulations, either processed by-products or synthetic material is used to form the aggregate. Expanded shale or clay – prepared shale or clay materials are heated, which expand the materials as the gasses within expand.

Construction aggregate - Wikipedia

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.

Lightweight Aggregate Concrete | Article about …

the most common type of concrete, in which lightweight aggregate is used as the coarse filler, cement (more rarely, gypsum, lime, synthetic resins) is used as the binder, and open sand or compact sand (for example, quartz sand) is used as the fine aggregate.

Green Home Building: Light-weight Concrete

Lightweight concrete may be made by using lightweight aggregates, or by the use of foaming agents, such as aluminum powder, which generates gas while the concrete is still plastic. Natural lightweight aggregates include pumice, scoria, volcanic cinders, tuff, and diatomite. Lightweight aggregate can also be produced by heating clay, shale, slate, diatomaceous shale, perlite, obsidian, and ...

Lightweight Aggregate Concrete | ScienceDirect

Publisher Summary. Lightweight aggregate concrete differs from the normal weight concrete because of its porous nature and lower strength. This fact is reflected on most of the properties; for example, on physical and mechanical behaviors.

Properties of Lightweight Concrete for Construction Works

Lightweight Concrete provides the same compressive strength as normal weight aggregates with approximately the same cement content. A typical performance chart of a given aggregate shows the various strengths attainable with different amounts of cement for both 7-day and 28-day tests (Fig. 1).

Lightweight Concrete Aggregate - Insucrete Concrete ...

Product Price : Get Latest Price. We offer Insucrete Concrete Aggregate. Loose Bulk Density -140 -160 kg/M 3 Almost ten times light weight than normal concrete, Insucrete now is the demand of green building application saving energy.

Lightweight Concrete | Classification of Lightweight …

Classification of Lightweight Concrete. There are three methods of producing lightweight concrete. First, porous lightweight aggregate whose specific gravity is approximately 2.6. The resultant concrete is generally known by the name lightweight aggregate used. The second method of producing lightweight concrete relies on introducing large voids within the concrete. These voids are clearly ...

Aggregate Size On Lightweight Concrete

Understanding the Density of Concrete - Aggregate Research. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.

LECA : Light Weight Concrete Aggregates

LECA is a special type of light aggregates that has been pelletized and fired in a rotary kiln at a very high temperature. As it is fired, the organic compounds are burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule melts and is sintered.


In conventional concrete, the percentage of sand in the aggregate is 30% to 40%. However, the foamed However, the foamed cement of this process/invention is preferably mixed with an aggregate having a higher ratio of sand.

Production Of Lightweight Aggregates Distroid Concrete

Riverlite® - Trinity Lightweight. Riverlite® expanded clay lightweight aggregate is produced to comply with the requirements of ASTM C330, Standard Specification for Lightweight Aggregates for Structural Concrete and ASTM C 331, Standard Specification for Lightweight Aggregates for Concrete …

Advances in Lightweight| Concrete Construction …

There are two ways saturated lightweight aggregate can help produce better concrete. First, with a typical mix, the transfer of moisture into and out of the lightweight aggregate particle prevents the buildup of a high w/c ratio area at the contact between the paste and the aggregate.
