Lightweight structural concrete.

Application

Can be used in any application where normal weight concrete is specified as follows: 

  • To create lighter concrete slabs, foundations, floors and walls.
  • To reduce loads on structures, or composite decking.

Description

Lightweight structural concrete produced using specialist engineered high strength lightweight aggregate and admixtures to provide much lower densities compared to standard conventional concrete.


Features and benefits:

  • Reduces the weight over conventional concrete by 30% (Structural) or 60% (Non-structural).
  • Can be produced with a density of 1800-1900 kg/m³.
  • Structural concrete strengths can be gained up to 50N/mm² compressive strength with non-structural mixes being possible with densities as low as 1000 kg/m³.
  • Reduces the need for propping on metal deck floors improving completion times.
  • Environmentally friendly – the lightweight aggregate is an expanded raw material, producing 300% more aggregate per cubic metre than quarried aggregates thereby reducing demand on natural resources.
  • Can be pumped and placed like normal weight concrete.
  • Improved fire resistance over normal weight concrete.
  • Can support the reduction in steel and foundation size in structures.
  • Improved thermal and acoustic properties over normal weight concrete.
  • Reduces cold bridging.
