Why CLC





What is CLC?


Cellular Lightweight Concrete (CLC) is conventional concrete where natural aggregate (gravel) is exchanged for the best insulation medium available, namely air, embedded in an organic and bio-degradable foam that solely serves as wrapping material for the air. The enzyme based foaming agent is derived from a highly active plant-based organic protein and does not contain any chemicals, chemical-induced substances, additives, or synthesized ingredients. Batches of cellular lightweight concrete are manufactured by combining key elements in an ordinary concrete mixer. The strength and dry density of the batch depend on the overall physical composition and air pocket content, and can be adjusted based on the proportions of the key ingredients included in the mix. Cellular Lightweight Concrete (CLC) is one of the most versatile concretes due to its various advantages and wide usage.

Advantages


  • Lower cost per square meter
  • Does not require plastering
  • Light in weight
  • Less steel required for foundation, columns & slabs
  • Increased productivity: faster & easier to build
  • Superior workability: can be drilled / sawn with conventional tools
  • Built-in conduits for mechanical, electrical & plumbing (no breakage needed)
  • Superior thermal insulation
  • Superior acoustic insulation
  • Low water absorption (no leakage or humidity in walls)
  • Lower energy costs on heating & cooling
  • Fire resistant (A1 rating per 'Eurospecs')
  • Eco-friendly: LCEC approved green product - Masonry envelope applicable for NEERA loan from Banque Du Liban



Applications


  • Interior & exterior walls
  • High rise buildings
  • Additional floors to existing structures
  • Thermal insulation roof slabs
  • Acoustic & thermal insulation floor slabs
  • Fire safety exit & stair case
  • Green construction

Global Usage


Cellular lightweight concrete (CLC), because of its special and versatile properties and application, is currently widely produced and used for building projects around the world. It’s easy to handle characteristics, superior insulation properties, and fire-resistant features, make it one of the most endorsed construction material by builders and architects around the globe. Additionally, it has special importance in the light of growing awareness related to environmental regulations and subsidies.

In recent years CLC has been used extensively in highways, commercial buildings, disaster rehabilitation buildings, schools, apartments and housing developments in countries such as Germany, USA, Russia, Brazil, Norway, Denmark, Singapore, India, Malaysia, Kuwait, Nigeria, Botswana, Mexico, Indonesia, Libya, Saudi Arabia, Algeria, Iraq and Egypt.

The use of lightweight concrete in the United Sates dates back to the 1900s. The Park Plaza Hotel in St. Louis was an early example of lightweight concrete construction in the 1900s. In the early 2000s, lightweight concrete has been used regularly in multistory buildings and other large structures. Some of the more notable structures are the Bank of America Corporate Center, Charlotte; the Watergate Apartments, Washington D.C.; and the Lake Point Towers, Chicago.
