What is the use of lightweight concrete?
Since the strength of LWC is low, it is used in the construction of roof slabs, small houses with load bearing walls etc. It is also used in the construction of stairs, windows, garden walls, etc. In large building construction this is used in the construction of partition walls.
What is lightweight concrete construction?
Standard concrete as a density of around 2300kg/m3 and Lightweight concrete generally has densities of less than 2100kg/m3.
What are the different types of lightweight concrete?
Understanding Different Types of Lightweight Concrete
- Low-Density Natural Aggregate Concrete. Most low-density aggregates are volcanic in origin and include pumice, tuff, scoria, and cinders.
- Processed or Synthetic Aggregate Concrete.
- Cellular or Aerated Concrete.
- High-Performance Concrete.
What are the three methods of producing lightweight concrete?
Structural lightweight concretes are produced using aggregates such as expanded slags [2]; sintering grate expanded shale, clay, or FA; and rotary kiln expanded shale, clay, or slate. These aggregates produce concretes that have densities ranging from 1360 to 1920 kg/m3 and minimum compressive strengths of 17.0 MPa.
What is lightweight concrete called?
Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar.
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.
What are the limitations of lightweight concrete?
The only disadvantage of Lightweight Concrete is that the depth of carbonation that is, the depth at which corrosion can occur within the right conditions is almost twice that of conventional concrete.
What is lightweight concrete?
Structural Concrete What is Lightweight Concrete? 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).
What is the density of a lightweight concrete slab?
Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³). Normal weight concrete a density in the range of 140 to 150 lb/ft³ (2240 to 2400 kg/m³).
What is lightlight concrete?
Light concrete is made of lightweight aggregate, it is also called foam concrete. Since this cement consists of lightweight aggregates, it is used in coarse aggregates and sand, clay, foamy slag, clinker, and crushed stone, aggregates of organic and inorganic. This concrete saves 15 to 20 % in the cost of construction of floors and roofs.
What is the best type of aggregate to use for lightweight concrete?
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.
