KOMPATIBILNOST SANACIJSKIH MORTOVA S POKRETNIM INHIBITORIMA KOROZIJE ARMATURE

COMPATIBILITY OF REPAIR MORTARS WITH MIGRATING CORROSION INHIBITORS

SAŽETAK

U radu su prikazani rezultati ispitivanja kompatibilnosti jednog pokretnog inhibitora korozije armature, dodanog u dva sanacijska morta, koji su izrađeni na bazi mineralnog veziva modificiranog polimerom. Ispitivan je utjecaj pokretnog inhibitora korozije armature na svojstva svježeg i očvrslog sanacijskog morta. Djelovanje pokretnog inhibitora glede zaštite armature od korozije ispitivano je prema normi ASTM G 109. Rezultati ukazuju, da je ispitivani pokretni inhibitor kompatibilan s ispitivanim sanacijskim mortovima i da odgađa pojavu korozije armature u betonu.

KLJUČNE RIJEČI: pokretni inhibitor korozije armature, sanacijski mort, polimerni dodatak

ABSTRACT

One of the possibilities for reinforced concrete corrosion protection is the application of migrating corrosion inhibitors as admixtures in repair mortars. The applied corrosion inhibitor must be effective for corrosion protection and compatible with polymers added to repair mort for improvement properties of fresh and hardened mortar. The paper reports the experimental results on compatibility of one migrating corrosion inhibitor added into two repair mortars based on inorganic binder modified with polymers. The influence of migrating inhibitor on the properties of fresh and hardened repair mortars were tested. The effectiveness on the reinforcement corrosion protection has been tested according to ASTM G 109. Test results proved that investigated migrating inhibitor is compatible with repair mortars and delay the time to the appearance of corrosion of reinforcement.

KEY WORDS: migrating inhibitor, repair mortar, polymer as admixture
