Lightweight Aggregate Concrete | ScienceDirect
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. Normally all concrete types are designed according to what concrete is sought.

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).
11.20 Lightweight Aggregate Manufacturing
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.
Understanding Different Types of Lightweight Concrete
While the description of lightweight concrete is fairly simple – lightweight concrete simply weighs less due to lower density aggregates than standard concrete, and can range from 35-100 pounds per cubic foot – it quickly becomes apparent that with both advances in technology and new materials being tested, lightweight concrete is not all created equal.
Lightweight concrete
The three main methods of production of lightweight concrete are: • The use of lightweight aggregates • The incorporation of voids by aeration • Little or no fine aggregate addition Lightweight aggregate concrete was generally be designed in accordance with BS 8110: Part 1.
Lightweight concrete
Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g LC30/33, which denotes a lightweight concrete with a …

Utilization of shale cuttings in production of lightweight ...
In view of this, the possibility to apply shale drill cuttings as a prospective additive (replacing bentonite) to fly ash used for the production of lightweight aggregates (LWAs) was investigated. Moreover, a facile, waste-free method of LWAs production with using shales was proposed.
Fly Ash & the Lightweight Aggregate Market
The beneficial reuse of fly ash offers a number of environmental benefits as well: The use of fly ash as a lightweight aggregate reduces the need for companies to mine virgin aggregate materials for use in concrete production. Landfilling has long been used as a primary approach to the disposal of fly ash.

Advantages and Disadvantages of Lightweight Concrete ...
Apr 12, 2018 · Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a stone of sand. This composition makes AAC highly suitable for pre-casting and reshaping.
