Zinc protective coatings on high carbon SWRH82B-1 steel were sherardized to markedly improve corrosion resistance of the high-strength steel bridge cable wires (SBCW). Sherardizing parameters have been optimized by optical microscopy (OM) /scanning electron microscopy (SEM), X-ray diffraction (XRD) and potentiodynamic polarization tests. The sherardizing coatings are composed of the loose outer layer (§-FeZn13 phase) and the dense inner layer (δ- FeZn7 phase) with higher hardness. Addition of Y2O3 activator slightly increases the corrosion resistance of sherardized steel wire in comparison with CeO2. A thicker coating corresponds to a higher sherardizing temperature or a longer heating duration, but an extra thick coating is unfavorable for thru-microcrack existed in the inner layer. Good quality of sherardized wires ( higher corrosion resistance and longer duration than conditional hot-dip-galvanized one) can be produced with the zinc-rich powder containing 7.5wt.% CeO2 activator and 25wt. % SiO2 filler under 400°Cfor 6h.

Cable Wire

Cable wire is characterized by light weight and high strength and is widely applied in long span bridges. However, steel cable wire is vulnerable to fatigue and corrosion, which has been proved to be true through collapses of several bridges because of cable failure. This paper will the following 4 types of the fractures of steel wire: cone-shaped fracture, serrated fracture, cup-shaped fracture and step-like fracture to explore failure cause of cable wire. This paper also illustrates the fracture feature respectively and failure causes considering environmental and loading condition of cable.

Steel Wire Mesh

The high strength steel wire mesh and polymer mortar reinforcement technology has the advantages of high strength, high temperature resistance,corrosion,resistant, etc. In this paper,we analysis the flexural properties of RC beams strengthened by it using ANSYS.To bear the same moment in the same area of the reinforcement steel strand, and then get effect of different span and different reinforcement methods (comparative beam, direct reinforced beams,and secondary load of reinforced beams) on flexural load-carrying capacity and deflection, then compare and analysis,and draws the conclusion which can provide reference for practical engineering.
