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.
The lightweight aggregate that results from the process is a safe, chemically neutral product with a wide range of uses in concrete manufacturing, building applications, road construction, and gardening. Owing to its physical properties, it has potentially wider application than natural aggregates. Its advantages are in

Dec 05, 2016 A new 15m lightweight aggregate facility has been built by Aggregate Industries. A leading supplier and manufacturer of construction and building materials, Aggregate Industries, has invested 15million into a new manufacturing facility within
Lightweight aggregate concrete is used in various types of construction because of its excellent properties. These properties include fire resistance, availability in a wide range of densities from 50 kgm3 to 1000 kgm3, excellent compressive strength, and possibility to cut, nail, drill, and shape the concrete with ordinary wood working tools.
In Building Materials in Civil Engineering, 2011. 1 Lightweight Aggregate Concrete. All kinds of light concrete that are made by light coarse aggregates, light fine aggregates or ordinary sand, cement and water are known as lightweight aggregate concrete. According to the types of aggregates, lightweight aggregate concrete can also be divided into full lightweight concrete both the coarse ...
a refuse-derived fuel RDF in the lightweight aggregate manufacturing process, energy consumption can be reduced and a sustainable resource can be reused 16,17. In addition, lightweight aggregates could be obtained with alternative low temperature processes, such as cold bonding pelletization 6.
In this study, the lightweight aggregate created with recycled WTS was shown to be applicable as concrete and filter media. In addition, it was possible to manufacture ultra-lightweight aggregates with a density of 0.8 g or less, but it is believed that additional research is needed to understand the lightweight mechanism.
Production Process Arcosa Lightweight begins with a raw material of select shale or clay, which is quarried at or near the companys manufacturing facilities. The raw material is processed by heating in rotary kilns at temperatures in excess of 2000 F under carefully controlled conditions.
Arcosa Lightweight has production facilities in California, Colorado, Texas, Louisiana, Indiana, Kentucky, Alabama and Arkansas. Arcosa Lightweight is a leading supporter of research, independent testing and field studies to improve the manufacturing process and expand the beneficial uses of
Arcosa Lightweight manufactured the structural lightweight aggregate used for the project at its plant in Frazier Park, California. The ready-mix supplier replaced the regular weight granite with the lighter material. The HydroLite lowers the concretes unit weight
A typical lightweight aggregate rotary kiln has a combustion gas residence time of 4 sec based on maximum temperature and a temperature range of 3701150 C 7002100 F. A typical rotary kiln processes approximately 450 Mg 500 tons of lightweight aggregate per day.
