THE INHIBITION OF THE CORROSION OF STEEL IN CONCRETE

LITERATURE ON THE CAUSES AND PREVENTION OF CORROSION IS FIRST REVIEWED. TESTS CARRIED OUT BY THE BUILDING RESEARCH STATION, GARSTON ARE THEN DESCRIBED. THESE WERE CARRIED OUT TO ESTABLISH: (1) THE NATURE OF THE CORROSION OF STEEL IN CHLORIDE-BEARING ALKALINE ENVIRONMENTS INHIBITED BY SODIUM NITRITE, (2) THE DIFFERENT EFFECTS PRODUCED BY SODIUM NITRITE AND SODIUM BENZOATE, AND (3) THE EFFECT OF INHIBITORS ON THE COMPRESSIVE STRENGTH OF CONCRETE TOGETHER WITH FIELD EXPOSURE TESTS. THE CORROSION AND CORROSION INHIBITION OF STEEL HAVE BEEN ASSESSED FROM: (1) IMMERSION TESTS WHERE THE RATE OF CORROSION IS MEASURED BY THE WEIGHT LOSS OF A SERIES OF SPECIMENS EXPOSED FOR DIFFERENT TIMES TO THE CORROSIVE ENVIRONMENT, AND (2) ELECTROCHEMICAL TESTS ON STEEL IN CONCRETE, WHERE STEEL SPECIMENS ARE MADE THE ANODE IN AN ELECTROCHEMICAL CELL, THE ATTAINMENT OF A STEADY POTENTIAL INDICATING PASSIVITY OF THE STEEL. /RRL/
