leggero – Light concrete

when plain concrete is not enough ...

Lightweight concrete is a material that combines good insulation properties and helps relieve built structures – it is lighter than standard concrete. It is produced with the application of lightweight aggregate and its density in the dry state is between 800 and 2000 kg / m3.

The production of lightweight concrete is done on the basis of lightweight aggregates, i.e. expanded clay aggregate, perlite, fly ash aggregate or polystyrene granules.

application:

Depending on the bulk density, lightweight concrete is used as an insulation material, insulation – construction material and design material. The product is used as follows:

  • downward layer and insulating layer of flat roofs and terraces
  • stuffer-insulating layer and relieving layer of the design for renovation of old floors
  • insulating alignment layer in floor heating systems
  • insulating layer above the last storey ceiling or above the cellar
  • elements of engineering structures, reducing the total weight of its own object
  • foundation pavements on bridges

advantages and benefits:

  • it reduces the total weight of the structure,
  • it relieves stress on the existing ceilings in for renovation of buildings for example historic buildings etc.
  • it improves the thermal insulation of floors, floors and roofs influencing the thermal energy savings
  • it easily fills the spaces around pipes and district heating protects against heat loss and mechanical damage
  • its insulating properties lead to savings on the expenditure resulting from subsequent additional finishing operation or in the case of making parts of ordinary concrete

technical and functional properties:

  • a density of from 800 to 2000 kg / m3
  • compressive strength from 2 to 35 MPa
  • application directly from concrete pump or trash transport using a crane
  • the possibility of pump feeding *
  • consistency allows for easy installation, leveling and appropriate compacting of the mixture
  • it suppresses sounds better than standard concrete
  • it has good thermal insulation properties
  • it adapts very well to uneven ground
  • lightweight concrete in the density class of D1.0 and D1.2 based on polystyrene granules
