Usage

Sika® Lightcrete-400 is particularly suitable for light-weight porous concrete:
  • Preferably with raw density of 0.5 - 1.5 kg/dm³
  • As thermal insulation
  • As a compensation / insulation layer in structural construction and civil engineering
  • As a light, flowable filling mix e.g. for excavations, old sewers, formwork blocks, etc.
  • For utilisation in recreational rooms
 

Advantages

With Sika® Foam devices SG 70 or SG S9 P, Sika® Lightcrete-400, water and air generate a stable foam. This foam is then mixed into the output concrete in the concrete mixer. The resulting air pore content in the mortar cause:
  • Low emission lightweight porous concrete
  • An easily workable, flowable consistency
  • Pumping capability due to stable air pores
  • A targeted bulk density setting and strength setting
An improved thermal insulation

Application

Application Information

Dispensing

The dosage of the Sika® Lightcrete-400, as well as the foam production and the addition of foam is executed via the Sika® Foam devices SG 70 and/or SG S9 P. The consumption of the foaming agent is approximately 150-230 g/100 litres of foam per device model. The required quantity of foam depends on the desired lightweight porous concrete bulk density. A uniform output consistency as well as sufficient mixing time must be taken into account when producing lightweight porous concrete. When pumping lightweight porous concrete with low bulk density, it is advisable to implement Sika® Stabilizer ST 3 in order to avoid possible pore destruction. Impurities such as e.g. oils, release agents, mixer protection or aluminium particles can cause an uncontrolled change the air pores salary.
