Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 .
Lightweight concrete is often the application of choice to reduce the dead load of a concrete structure, allowing the structural designer to reduce the size of architectural elements like columns, footings, and other loadbearing structures. By using this unique concrete mix, you reduce the need for steel reinforcements and lower the overall volume of concrete required, which can result in lower

In addition, lightweight concrete is noncombustible, soundabsorbing and particularly economical. With Poraver® expanded glass granules as an aggregate, lightweight concrete becomes a purely mineral and ecological building product which can simply be recycled if needed.
Lightweight aggregates, such as clay, shale or slate materials, are typically used to make structural lightweight concrete. These lightweight aggregates are fired in a rotary kiln to cause this type concrete to have a porous structure. Aircooled blast furnace slag may also be used to create lightweight concrete aggregates.
