Corrosion Properties and Bond Strength of Coated (PE/PAK; PE/PPE; PAD) Reinforcement (B500B) with Normal Strength Concrete
Original language description
The paper verifies anti-corrosion barrier protective properties of PE/PAK (polyethylene/polyacrylate), PE/PPE (polyethylene/polyproplylene) and PAD (polyamide) coatings of specific thickness on the surface of conventional ribbed bar B500B. Using pull-out test, the bond strength of such system was compared with bond strength of normal strength concrete (C30/37). Results of these tests show that key properties of coated systems are comparable to the previously tested epoxy coatings in case of their use in technical practice (protection of conventional rebar). In conclusion, their effective protective effect corresponds to minimal thickness higher than 300 µm but simultaneously lower the bond strength between the ribbed rebar and concrete.
