Classification of Aggregates. The variability in density can be used to produce concrete of widely different unit weights, see Table (1). The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates.
Determination of particle density of lightweight aggregates with porous surface PETER MAYDL Technische Versuchs- und Forschungsanstalt, Technische Universit& Wien, Austria Particle density is one of the most important values to characterize lightweight aggregates. Various test methods yield various densities, because the grain volume is defined by the test fluid used to determine the volume …
No single description of the ESCS aggregate material is all-inclusive, and the reader is urged to consult the individual ESCS manufacturers for physical and mechanical properties of their lightweight aggregates, as well as for the proper use in the various aggregate applications.
Lytag produce a range of aggregates for various construction solutions. We can produce bespoke mixes if required.
mechanical properties of lightweight aggregate concrete (LWAC) are discussed in this paper. The fly ash content ranged The fly ash content ranged from 18% to 22% by cement volume, and the water-cement ratios are set to 0.3, 0.33 and 0.36 for each type of LWA.
LECA and LYTAG Lightweight Aggregate - Man-made aggregate which is produced by sintering clay or pulverised ash particles. The aggregate is spherical with a honeycomb centre and a ceramified surface and range from 2mm to 20mm in size. These are graded to meet various end uses.
These lightweight plastic aggregates were then used as substitute for natural aggregates at percentages of 0%, 3%, 6%, and 9%. Recyclable plastic bags measuring 10–20 mm were gathered then heated in an oven
For example various lightweight aggregates, even those produced by similar processes, require a considerable range in cement contents to produce concrete having equivalent strengths. Thus there is some logic in looking to the manufacturer of a particular material for recommendations concerning trial mix proportions. Other characteristics are: the modulus of elasticity ranges for one and a half ...
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
Appropriate lightweight aggregates are different depending on what part of the country one is in. Q : Can you tell me an easy way to aerate concrete with or without chemicals, as here in Indonesia chemicals & pumice etc. are hard to obtain!!
Lightweight aggregates Up to 50% lighter than conventional building aggregates, the lightweight aggregate stocked and supplied by MCM offers a natural alternative material for construction and civil engineering projects.
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.
In the U.S., lightweight concrete became more common around the 1930s and continues to provide advantages to the building and creative industries as different types of lightweight concretes are developed for use. Those advantages include not only weight considerations, but also insulation value, sound reduction, and workability.
Lightweight aggregate is the generic name of a group of aggregates having a relative density lower than normal density aggregates (natural sand, gravel, and crushed stone), sometimes and is referred to as low density aggregate.

-Lightweight aggregates from blast furnace slag ( Palletized slag) ... There are different types of cements varying in their mineralogical compositions. The addition of mineral admixtures like silica fume produces cement with high strength. This is of interest for off-shore construction where high strength and high performance are required. A Norwegiancement company (NORCEM) has developed high ...
Concrete sidewalk stamped with contractor name and date of placement. Concrete is produced in a variety of compositions, finishes and performance characteristics to meet a wide range of needs.
lightweight aggregates produced from recycled glass. The developed ultra-lightweight concrete, with a dry density of about 650–700 kg/m 3, shows excellent thermal properties, with a thermal conductivity of about 0.12 W/(m K); and moderate mechanical prop-
Lightweight concrete, also sometimes referred to as low-density concrete, is made using the same basic ingredients as any concrete – water, Portland cement and aggregate – but the difference lies in the aggregate.
different Lightweight aggregates and Lightweight concretes such as sintering, autoclaving and cold bonding etc. These Lightweight Concrete materials can be used in various applications like masonry blocks for high rise buildings, wall panels for multi-storey buildings, heavy buildings structures, lightweight structures etc in the utilization of the materials and for efficient purposes. Further ...
Atrium Lightweight Materials Inc. We are a supplier of lightweight aggregates throughout Alberta and Western Canada. In Calgary we are the exclusive supplier of AGGRELITE ™ and granulite lightweight expanded shale which is used in various geotechnical applications involving underground pipe insulation in shallow utility applications.

The different types of lightweight aggregate, natural and manmade, need to be carefully examined before use for the production of concrete. The properties of the aggregate, such as the bulk density, the particle density, the moisture content, and the size distribution by sieve analysis, are to be determined before production.
In the present study, lightweight expanded clay aggregates were produced from clay, waste brick powders, albite floatation waste, and coal at various temperatures ranged from 900 °C to 1250 °C.
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.
