Degradation of bond strength due to corrosion of steel strands is of great importance for serviceability of prestressed concrete structures. An analytical model is proposed to demonstrate the effect of corrosion of steel strand on reduction of bond stren
The elemental composition of the specimen's surface was inspected using the XPS technique, to provide evidence about the nature of the adsorption process of the inhibitive layer on the C-steel surface. In this way the type of chemical bonding on the surface of carbon steel was recorded. XPS ...

The steam could be reused in an existing steam system in the steel industry or used for power generation, while the syngas could be used for power generation or chemical engineering18,19,20. Scheme 1 shows a final energy efficiency of 62%, but Schemes 2–5 produce less steam and more ...
To further determine the microstructure and chemical composition of samples, high resolution transmission electron microscopy (HRTEM, Themis) with mapping scanning energy dispersive X-ray spectroscopy (EDS) was employed. Before HRTEM test, the surface of samples were subjected strong ultrasonic peeling in...
