Lightweight concrete is a special concrete that has a lower density compared to conventional concrete. The term “lightweight concrete” is made up of the words “light” (low weight) and “concrete” (a building material made from cement, sand, gravel and water). There are various methods for producing lightweight concrete, with the main goal being to reduce the weight of the concrete without greatly compromising its strength and other important properties.

There are several types of lightweight concrete, including:

• Lightweight concrete with bulk densities between approx. 800 and 2000 kg/m³:
  • Wall elements and panels are also classified in this product range.
• Lightweight concrete with bulk densities between approx. 300 and 800 kg/m³:
  • The usual field of application here is primarily in the area of ​​load-bearing wall systems.
• Ultra-lightweight concrete with bulk densities between approx. 90 and 350 kg/m³:
  • Insulation panels and lightweight stones are primarily found in this area. In addition to insulation applications, these products are also increasingly being used in the area of ​​high-rise construction, as their low weight is of particular importance here.

The benefits of lightweight concrete include better thermal insulation, lower weight, improved sound insulation and, in some cases, better workability. These properties make lightweight concrete attractive in various applications, including building construction, facades, ceilings, roof structures and other construction projects where the weight of the material is a consideration.
