Effectiveness of Super-plasticizer on High Volume Fly Ash Concrete

This research project was aimed to determine the optimum super-plasticizer dosage for producing highly workable, high strength, low porosity and low gas permeability concrete containing high volume fly ash ( 60%) as partial cement replacement. The trial mix with 100% cement was initiated with a w...
