Phase 3: Concreting

 

  • Check the formwork assemblies and related shoring before concreting begins.
  • From this point on, once concreting has begun, do not change the shoring level settings.
  • Position the concrete skip above the distributor.
  • Continuous pouring of inner and outer walls with self-compacting concrete (SCC), Ultra Twins GBE System® by Lafarge.
  • Both faces are poured simultaneously, taking care to pour the least thick face (external face) more rapidly.
  • The concreting speed varies according to the ambient temperature and the wall thickness (in accordance with requirements stipulated by the ready-mix concrete supplier).
  • Check the verticality of the formwork after pouring.

NB*: LAFARGE Ultra Twin GBE System® concrete enables heights of up to 5 meters to be poured without a plunger tube in 10 cm facing wall (minimum).

 

NB**: For projects that require aesthetic facing walls, please refer to the implementation suggestions from the ready-mix concrete supplier.
