PREDNOSTI I NEDOSTACI NOVIH TEHNOLOGIJA ZAŠTITE ARMATURE U BETONU

ADVANTAGES AND DISADVANTAGES OF THE TECHOLOGIES FOR THE PROTECTION OF STEEL REINFORCEMENTS IN CONCRETE

SAŽETAK

Postupci zaštite armature u betonu mogu se razgraničiti na dvije mogućnosti: zaštita betonom ili zaštita same armature U radu su opisani mehanizmi djelovanja inhibitora korozije armature u betonu i princip djelovanja katodne zaštite. Dan je kritički osvrt na prednosti i nedostatke za obje metode kada se primjene kao metode zaštite armature u armirano betonskim konstrukcijama.

KLJUČNE RIJEČI

SUMMARY

Methods of protection the reinforcing steel in concrete are divided into two possibilities: protection of concrete or protection of reinforcing steel. In this paper the activity mechanisms of migrating corrosion inhibitors for reinforcing steel protection are described. The mechanism of the cathodic protection is also given. Critical overview on the advantages and disadvantages of these methods, which are used to protect the steel.
