Effect of calcium hydroxyzincate on bond strength of hot-dip galvanized plain bars with normal strength concrete
Original language description
The study separately investigates the interaction of two primary effects causing reduction of the bond strength between hot-dip galvanized steel and normal strength concrete. The effect of the layer of calcium hydroxyzincate (CHZ, commonly forming on hot-dip galvanized steel in concrete) is newly examined. It is shown that increasing the porosity of cement at the phase interface has a smaller negative effect on the bond strength than the presence of a thick layer of the CHZ corrosion products. The failure mechanism of corroded hot-dip galvanized plain bars during bond strength testing differs from that of uncoated steel as the intergranular rupture is likely formed at the CHZ/cement phase interface, or at a small depth below the interface in the CHZ crystals.
