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...

Abstract With the rise of interest in digital fabrication reinforced concrete structures, a great number structural designs that depart from standard prismatic shapes are being suggested. This has prompted an exploration steel reinforcement strategies alternative to classical deformed or “ribbed” rebars. One such is cut internal plates using waterjet cutting machine. Advantages automated includ...

in this study, in order to investigate the effect of increasing the manganese content on microstructure and mechanical properties of high manganese austenitic steels, three alloys with successive increases in weight percentages of manganese (7.55, 13.1, and 16.5) and carbon (0.8 and 1.2) were cast in the presence of a constant amount of chromium (1.5 wt.%) and silica (0.6 wt.%). the samples exp...

In this paper, a novel kind of method to monitor corrosion expansion of steel rebars in steel reinforced concrete structures named fiber optic coil winding method is proposed, discussed and tested. It is based on the fiber optical Brillouin sensing technique. Firstly, a strain calibration experiment is designed and conducted to obtain the strain coefficient of single mode fiber optics. Results ...

workers who carry out manual rebar tying tasks are exposed to muscular-skeletal injuries associated with the use of manual tools and the movements associated with them (force, repetitiveness and awkward wrist postures). this paper presents a background on musculoskeletal injuries directly linked to manual and mechanical rebar tying method is conducted. the objective of this study is to compare ...

To assess the condition of structures buildings and structures, a comprehensive analysis factors affecting their performance characteristics - concrete strength, protective layer, rebar diameter, thermal conductivity moisture content concrete, adhesion facing coatings, frost resistance water is required. However, with all variety monitored parameters control strength has special place because w...

This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
