barsA limited number of investigations have been carried out to assess the cyclic bond behaviour of reinforcing steel bars in underwater concrete (UWC). An experimental campaign with 57 pull-out specimens was undertaken, testing one mixture previously developed and characterized to be used in a ...
Steel Testing Equipment The majority of the proposed models concern the tension test of reinforcing bars. In particular, the High capacity steel tensile testers have been specifically designed to test reinforcing bars. The front loading of specimens, the hydraulic gripping system, the remote control ...

In addition to their high strength and light weight, fiber-reinforced polymer (FRP) composite reinforcing bars offer corrosion resistance, making them a promising alternative to traditional steel reinforcing bars in concrete bridge decks. FRP reinforcement has been used in several bridge decks recently ...

2. In the columns, S500 Class B reinforcing steel (fyk=500MPa) was used, with the exception of the column bases, where B450C is placed. The steel yield strength of the punching reinforcement studs was fyk=500MPa. Table 1. Concrete Testing (cubes). Structural elementsfcRcst.devsamples ...
Pullout Performance of Fully and Partially Bonded Retrofit Anchors in Low-Strength Concrete In the seismic retrofit of reinforced concrete structures, steel reinforcing bars are often used as post-installed chemical anchors to integrate new struct...

This equipment is an ideal test equipment for steel works and construction units to test the forward and backward bending properties of steel bars. The bending testing machine of reinforcing bar is characterized by compact structure, simple operation,...
To confirm its lateral-load-resisting and seismic performance, reversed cyclic tests of two two-thirds-scale PC T-walls with and without diagonal reinforcing bars were conducted under displacement control. Test results showed that the T-wall specimen without diagonal reinforcement performed reasonably ...
Factors such as poor design, bad workmanship and a harsh environment can combine to cause deterioration within a concrete structure leading to visually unacceptable surface cracking or spalling of concrete cover [. In aggressive environments, corrosion of steel reinforcing bars is responsible for major ...
