PROTECTION OF CONCRETE REINFORCEMENT IN CRACKS BY MEANS OF CORROSION INHIBITORS

ZASCHITA ARMATURY V TRESHCHINAKH BETONA PRI POMOSHCHI INGIBITOROV KORROZII

A study was carried out of the rate of corrosion of reinforcement in fissured concrete and of the effect of adding nitrate-calcium nitrite (nnk). The addition of nnk decreases the depth and surface area of corrosion. An investigation was also conducted into the rate of carbonation of concrete containing nnk. It was shown that this additive decreases the rate and depth of carbonation thus increasing the protection of the reinforcement. The process is explained in detail. /TRRL/
