SAE 1020 is a widely used plain carbon steel, as mortar reinforcement in buildings and small machine parts. But aside from good mechanical properties, its surface suffer from severe corrosion and high wear rate, due to modest hardness. Chromium (Cr) in excess of 12% in Fe alloys renders them resistant to several corrosive attacks. So we tried to introduce Cr in such amounts into the surface of ...

Abstract—In the previous airfield construction industry, pavements made of reinforced concrete have been used very rarely; however, the necessity to use this type of pavements in an emergency situations justifies the need reference to this issue. The paper concerns the problem of airfield pavement dimensioning made of reinforced concrete and the evaluation of selected dimensioning methods of re...

This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...

This paper reports on nine relevant applications of FRP composites in concrete structures in the United States. Strengthening of concrete members with externally bonded FRP laminates or near surface mounted (NSM) bars has received remarkable attention. FRP materials have been used in small projects and some multi-million dollar projects for strengthening parking garages, multi-purpose conventio...

Borated water leakage through spent fuel pools (SFPs) at pressurized water reactors is a concern because it could cause corrosion of reinforcement steel in the concrete structure and compromise the integrity of the structure. Because corrosion rate of carbon steel in concrete in the presence of boric acid is lacking in published literature and available data are equivocal on the effect of boric...

Acoustic emission (AE) technique is used for monitoring and evaluating the influence of corrosion on the structural behaviour of steel reinforced concrete (RC) beams under three-point flexure test. In this study, steel corrosion was accelerated by electro-chemical method utilising a direct current (DC) power supply and 5% sodium chloride (NaCl) solution. The steel corrosion that was induced int...

Between 1978 and 1998, a total of 38 consecutive acetabular component revisions were performed in 38 patients. Average age was 67 years, and 87% of patients had severe uncontained segmental acetabular defects of more than 50%. We describe the operative technique of acetabular component revisions performed with bone grafting and a steel, semirigid acetabular reinforcement ring (Eichler), and lon...
