Lightweight aggregates manufactured from grinding, pelletising and sintering of MIBA were comparable to the commercial Lytag (produced from coal fly ash) in terms of density and water absorption, though with slightly lower strength. Blocks containing MIBA as an aggregate satisfied the requirements for a range of uses including load-bearing/non ...
Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds, the microstructure with different binder systems, and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete.
The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete. Foamed concrete
Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is 3295; there currently is no Source Classification Code (SCC) for the industry.

Our lightweight aggregate has achieved a thermal conductivity as low as 0.067 W/mk and is suitable for indoor and outdoor applications.
Lightweight aggregates: As mentioned in the body of this paper, lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg/m 3.The lightweight is due to the cellular or high internal porous microstructure, which gives this type of aggregate a …
Lightweight aggregates suitable for structural concrete may be natural materials such as pumice or scoria, or they may be processed aggregates such as expanded shales, clays, slates, and slags. More porous than normalweight particles, lightweight aggregates that are not presaturated will absorb the water in the concrete mix.
Lightweight Applications. STALITE manufactures the finest high performance lightweight aggregate in the world.Each of the applications described within this website will have specifications, test reports and research available for users to download.
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. Aggregates are the most mined materials in the world.
Global Lightweight Aggregate Concrete Market: Overview . Lightweight aggregate concrete Market is a type of concrete, which includes an expanding agent. The expanding agent helps increase the volume of the mixture, while simultaneously reducing its dead weight. The expanding agent can be termed as lightweight aggregate.
Most low-density aggregates are volcanic in origin and include pumice, tuff, scoria, and cinders. Diatomite is also something used as the aggregate component of lightweight concretes. The advantage to these types of aggregate is that they often do not require processing apart from crushing or screening.
Nov 13, 2017· Lightweight aggregate (sometimes is called as low density aggregate) is a generic name of a group of aggregates for structural concrete, mortar, or plaster that weighs less than usual rock aggregates including natural sand, gravel, and crushed stones. At an earlier stage, lightweight aggregates were mainly from natural origin, mostly volcanic pumice, tuff, etc.
Ultra-Lightweight Foamed Glass Aggregates are produced from post-consumer recycled glass. The aggregates have a highly frictional surface and combined with a low unit weight, inertness, high permeability, and insulating properties, foamed glass aggregate is ideal as a lightweight backfill.
Description: Specifies a method for the determination of the bulk density of dry or moist aggregates (normal or lightweight) for concrete in either loose or compacted condition.Describes apparatus, sampling, determination of uncompacted and compacted bulk density, expression of results, and test
Jul 18, 2011· The use of lightweight aggregates may have an impact on the compressive strength of the concrete. Highly absorptive lightweight aggregate should be wetted at least 24 hours prior to use. It is not recommended that dry lightweight aggregate be directly batched and mixed because the aggregate particles can continue to absorb water from the mix.
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).
ESCS Product Expanded shale, expanded clay and expanded slate (ESCS) lightweight aggregate is prepared by expanding select minerals in a rotary kiln at temperatures over 1000° C. The production and raw material selection processes are strictly controlled to ensure a uniform, high quality lightweight aggregate. ESCS gives designers greater flexibility in creating solutions to meet …

Abstract. This specification covers lightweight aggregates intended for use in concrete not exposed to the weather, in which the prime consideration is the thermal insulating property of the resulting concrete.
Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
In this article, we'll take a brief look at the most popular lightweight aggregates for concrete, and discuss which ones may be right for you. Expanded Glass Aggregate. Expanded glass aggregate is a type of lightweight aggregate that is composed primarily of recycled glass.
The use of fly ash as a lightweight aggregate can offer a wide range of economic advantages; not only is the source of fly ash (power plants) close in proximity to the demand, providing a readily available aggregate source at hand, but it can also be a much-needed economic source in areas where natural aggregates are not widely available.
