STRENGTH AND CORROSION RESISTANCE OF SUPERPLASTICIZED CONCRETES

A laborotary evaluation was made of the strength development and long-term corrosion resistance of concretes made with two fly ashes and one natural pozzolan in conjunction with a chloride-free superplasticizer. Addition of superplasticizer to plain cement concrete resulted in an increase in the compressive strength up to 90 days. This is due to the reduction in the quantity of water by about 32%. The 90-day compressive strength of concretes in which 20% of the cement was replaced with pozzolans was less than that of the plain portland cement concretes. These and other conclusions drawn from the study are discussed.
