  1. 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 TAMUK

  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 TAMUK

  4. 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. TAMUK

  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.
