With the advent of superplasticizers, dream to discover method of making ready mixed concrete at the lowest possible water cement ratio
while maintaining a high workability has achieved. In addition, these concrete material are also suitable for use with other cementations
materials like fly ash. Poly(styrene-co-acrylonitrile) prepared with the help of p-acetyl benzylidene triphenyl arsonium ylide had made it
possible, the production of concrete at low water cement ratio. Many waste materials of today become the useful by products of tomorrow
water cement ratio was maintained between 0.38-0.47. Use of fly ash in concrete improves the penetration rate of CO2 or chloride ions. The
result have shown substantial improvement in the properties of concrete after use of copolymer of styrene and acrylonitrile as
superplasticizer.
Key words: p-Acetylbenzylidenetriphenylarsonium ylide (p-ABTAY), ready-mixed concrete (RMC), fly ash, water cement ratio,
styrene, acrylonitrile, copolymer
