2. WHY POLYMER CONCRETE
• DIFFERENT DRAWBACKS OF CONCRETE
• REDUCING THE DRAWBACKS
• ALTERNATIVE TO CONVENTIONAL CONCRETE
• REDUCE GREEN HOUSE EFFECT
• REDUCE ENERGY CONUMPTION
12. The aggregates are prepared in saturated-
surface-dry (SSD) condition, and are kept in
plastic buckets with lid
13. The fly ash and the aggregates are first mixed
together dry in 80-litre capacity pan mixer
. Pan Mixer Used in the Manufacture of Geopolymer
Concrete
14. The liquid component of the mixture is then added to the dry
materials and the mixing continued usually for another four
minutes
Addition of Liquid Component
15. The fresh concrete could be handled up to 120 minutes
without any sign of setting and without any degradation
in the compressive strength

32. CONCLUSION
• The reduced CO2 emissions of Geopolymer cements
• a good alternative to Ordinary Portland Cement.
• comparable to or better than traditional cements with
respect to most properties.
• Rapid curing, excellent bond to cement concrete and
steel reinforcement, high strength,permeability,corrosion
and durability
• vary with temperature and polymer used.
• The strength of polymer-modified concrete is greatly
influenced by the mixing ratio of ingredients and type of
the polymer used.
• The strength and toughness of polymer concrete also
increase with addition of fibers
• Size of aggregates,microfiller
• Low maintenance
• Still there is no polymer to serve universal purposes
33. PLACES OF APPLICATION
• hazardous waste containment,drains,manholes,acid
tanks
• swimming pools, tunnel lining, shells, floor tiles,
• 70–75% of its strength after a curing of one day at
room temperature
• The early strength gain is important in precast
applications because it permits the structures to
resist higher stresses early due to form-stripping,
handling, transportation, and erection operations
• Quick setting time
• Environmental safety
34. FUTURE SCOPE
• cheaper polymers may be made for this purpose
• Further developments may lead to common usage
• alternative and potential replacement for OPC
• reducing the greenhouse emissions
• Creating awareness
