WHY POLYMER CONCRETE

• DIFFERENT DRAWBACKS OF CONCRETE

• REDUCING THE DRAWBACKS

• ALTERNATIVE TO CONVENTIONAL CONCRETE

• REDUCE GREEN HOUSE EFFECT

• REDUCE ENERGY CONUMPTION

MIXING

The aggregates are prepared in saturated-

surface-dry (SSD) condition, and are kept in

plastic buckets with lid

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

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

The fresh concrete could be handled up to 120 minutes

without any sign of setting and without any degradation

in the compressive strength

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,corrosionand 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

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

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
