REINFORCED CONCRETE - PROTECTION OF THE REINFORCEMENT

BETON ARME - PROTECTION DES ARMATURES

This article studies the influence of zinc and the salts it contains on concrete as regards adhesion. It describes laboratory tests on new steel, oxidized steel and zinc treated steel, together with commercial applications in France, the Netherlands, the United States, Japan, etc. It deals with the reaction of zinc with cement and with the consequence on the behaviour of steel wires subjected to high tensile prestressing forces. Mention is made of full-scale tests on prestressed beams. The risk of brittleness in high-strength steel due to the presence of hydrogen released through the reaction between zinc and cement, can be avoided if the appropriate type of cement is used or by adding potassium bichromate to artificial portland cement. /TRRL/
