NEW ADMIXTURE FOR CONCRETE WHICH PROTECTS REINFORCEMENTS AGAINST CORROSION IN AGGRESSIVE MEDIA

THE ADDITION OF A MIXTURE OF NITRITE AND CALCIUM NITRATE TO FRESH CONCRETE EFFECTIVELY SLOWS DOWN THE CORROSION OF REINFORCEMENT IN CONCRETE CONTAINING AGGRESSIVE CHLORIDE IONS. IF THE ADMIXTURE IS ADDED TO THE PASTE IN EQUAL QUANTITY TO THAT OF THE CHLORIDE CONTENT OF THE CONCRETE, THE RISK OF CORROSION OF THE REINFORCEMENT IS PRACTICALLY ELIMINATED. AN EFFECTIVE METHOD OF PROTECTING THE REINFORCEMENT OF REINFORCED CONCRETE STRUCTURES FROM CORROSION IN AN AGGRESSIVE MEDIUM IS (AS WELL AS APPLYING COATS OF PAINT) TO ADD THE ABOVE ADMIXTURE TO FRESH CONCRETE IN THE PROPORTION OF 2 PERCENT OF THE CEMENT WEIGHT. /TRRL/
