Abstrakty

The experimental methods for determination of concrete resistance to chlorides – both the chloride permeability test methods (NT Build 492 NordTest – Non-S teady State Migration Test, AASHTO T 277-ASTM C 1202 Test) and the methods for testing concrete resistance to surface scaling due to cyclic freezing and thawing in the presence of NaCl solution (deicing salts, saline sea water, etc.) (e.g. Slab Test according to CEN/TS 12390-9, based on the Borås method according to Swedish Standard SS 13 72 44) are presented in the paper. The Rapid Chloride Test – the method used "in situ" to determine the chloride ion content in concrete is also described.

W artykule przedstawiono doświadczalne metody określenia odporności betonu na działanie chlorków – metody badania przepuszczalności chlorków (NT Build 492 NortTest – Test migracji chlorków przy nieustalonym przepływie, AASHTO T 277-ASTM C 1202 Test) oraz metody badania odporności betonu na powierzchniowe łuszczenie spowodowane cyklicznym zamrażaniem i odmrażaniem w obecności roztworu NaCl (soli odladzających, słonej wody morskiej itd.) (np. Slab Test według normy CEN/TS 12390-9, wzorowany na metodzie Borås według szwedzkiej normy SS 13 72 44). Opisano również Rapid Chloride Test – metodę "in situ" badania zawartości jonów chlorkowych w betonie.
