CORRODIBILITY OF PRESTRESSING WIRE IN CONCRETES MADE WITH TYPE I AND TYPE IS CEMENTS

FIVE ASTM TYPE IS AND 3 TYPE I CEMENTS WERE USED IN A STUDY WHICH COMPARED THE CORRODIBILITY OF PRESTRESSING WIRE IN CONCRETES MADE WITH AND WITHOUT CALCIUM CHLORIDE. FOR PERIODS OF EXPOSURE TO ONE YEAR, THE BEHAVIOR OF THE WIRE WAS FOUND TO BE ESSENTIALLY THE SAME FOR THESE 2 TYPES OF CEMENTS. THE ADDITION OF 2 PERCENT CALCIUM CHLORIDE CAUSED A SIGNIFICANT INCREASE IN CORROSION AT 12 MONTHS. /PCA/
