LABORATORY CORROSION TEST OF STEEL IN CONCRETE: INTERIM REPORT

A METHOD FOR LABORATORY CORROSION TESTING OF STEEL IN CONCRETE WAS CORRELATED TO PREVIOUS LABORATORY AND FIELD INVESTIGATIONS. INCLUDED IN THE REPORT ARE DERIVED MATH- EMATICAL RELATIONSHIPS OF THE INFLUENCE OF MOIST OR STEAM CURING, ADMIXTURES, MIXING WATER, ENTRAINED AIR, AND CEMENT CONTENT OF CONCRETE TO THE TIME OF AN ACTIVE HALF-CELL POTENTIAL OF THE EMBADDED STEEL. SOME STATISTICAL DATA ARE PRESENTED WHICH INDICATE THE NUMERICAL VALUE WHICH DEMARKS THE UPPER LIMIT OF A PASSIVE HALF-CELL POTENTIAL OF THE STEEL. OTHER DATA SHOW THE MEASURED CORROSION LOSS OF THE STEEL AND THE QUANTITY OF CHLORIDE FOUND IN CONCRETE FRAGMENTS. ALSO PRESENTED IS WHAT IS BELIEVED A NEW METHOD FOR APPLYING A REGRESSION ANALYSIS TO THE DISTRIBUTION OF TEST VALUES.
