What are lightweight aggregates used for?

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.

What is light weight concrete and what are its advantages?

Lightweight concrete can be defined as a type of concrete which includes an expanding agent in that it increases the volume of the mixture while giving additional qualities such as nailbility and lessened the dead weight. The main specialties of lightweight concrete are its low density and thermal conductivity.

What are the properties of lightweight concrete?

Lightweight concrete is characterized by good compressive strength, durability and the most important advantages – low density and improved properties of thermal conductivity. Typical lightweight concrete aggregates are expanded clay or shale, natural porous materials like vermiculite or pumice.

Can lightweight concrete be used outside?

No-Fines concrete is best-suited for load bearing walls and can be used for both indoor and outdoor constructions. However, this type of lightweight concrete should not be used with reinforced concrete, especially due to its lower density and cement content.

What aggregate is used in lightweight concrete?

Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³.

What is lightweight concrete aggregate?

The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement. The lightweight concrete is also known to absorb very little water and can maintain the low density.

How light weight concrete is developed and mentions its application?

It can be produced with the use of naturally mined lightweight aggregates (bulk density in the range of 880 kg/m3) or manmade lightweight aggregates like “Aardelite” or “Lytag” (bulk density 800 kg/m3). Using foaming agents: This one is produced through the addition of a foaming agent in cement mortar.

What is the lightweight concrete?

Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. It is being increasingly used to build sleek foundations, and has emerged as a viable alternative to regular concrete.

Is lightweight concrete stronger than regular concrete?

Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³. Nevertheless, a higher compressive strength of 7000 to 10,000 psi can be attained with lightweight concrete.
