Concrete Foam

• Materials Science(MEEN 3344)
• By
• Uduzei M. Ovbiagele (Duz)

2
Preparation/Development

• Cellular/Lightweight Concrete
• Base material foam Concrete foam
• Base material Portland cement which could be
  improved for strength , quality environment.
• Foam Foaming generator, foaming agent, water
  air
• Prepared mostly by 2 methods
• Mixed Foaming
• Pre-forming
• Its strength performance depends on the
  density, mixing ratios constituent materials

3
Applications

• Roofing Insulation
• Engineering /Floor Fills
• Road Sub-base
• Lightweight precast blocks
• Fire breaks/Sound insulation
• Tunnel construction /refurbishing
• Bridge Abutment
• Soil stabilization/replacement

WHY CONCRETE FOAM(Operational Cost
Efficiencies)

• Reasonably high strength with accompanying low
  density and forming rigid well bonded structures.
• High fluidity and settlement compaction free
  construction.
• Time saving due to rapid installation, applied
  directly on marginal soil, no waiting for
  consolidation of top soil.
• Can be designed for a specific project budget
  requirements.
• Reduced lateral loading which cut cost for earth
  retaining structures.
• Durability of the foam non requirement of sand
  drain, piling grade beams reduces maintenance.

5
Conclusions

• Concrete foams are more suitable for certain
  applications when compared to regular concrete.
• Its strength and performance depend on it density
  and constituent materials.
• When it is being applied to projects which it is
  suitable for it makes better financial sense than
  its alternatives.
• Its suitability for certain projects are tied to
  its properties such as been lightweight fluid.
