“…The same scatter in material characteristics between SCC and VC made with the same W/CM was also observed in the pull-out tests of Mendez et al [3], where the normalised mean bond strength in 30 MPa specimens is higher in the case of SCC specimens comparing with VC ones. However, in the case of 60 MPa specimens, for 10 mm bars, the VC has stronger bond and for the 16 mm bars, higher bond strength was observed in SCC specimens.…”

“…Menezes et al [3] analysed the bond behaviour of SCC in comparison to VC using pull-out and beam tests according to RILEM procedures. The testing program considered bar sizes of 10 and 16 mm and VC and SCC with compressive strengths of 30 and 60 MPa.…”

Proper force transfer between the reinforcement and surrounding concrete is one of the most significant factors affecting the structural behaviour of reinforced concrete structures. Due to the importance of this issue, there is lots of research devoted to investigating the bond properties of conventional vibrated concrete mixtures. This chapter presents a comprehensive review of different aspects of bond properties of self-compacting concrete (SCC).In the first part of this chapter, bond strength to reinforcing bars and prestressing strands is reviewed, including the top-bar effect for various types of SCC mixtures. The effect of using chemical admixtures, such as viscosity-modifying admixtures (VMAs), to reduce the top-bar effect is discussed. The effect of using supplementary cementitious materials (SCMs) and fillers on bond strength characteristics of SCC is reviewed. Bond strength between successive lifts of SCC in multi-layer casting is reviewed highlighting the effect of elapsed time between the castings of different layers and the thixotropy of the lower lift on bond in multilayer casting. Finally, bond strength characteristics between SCC mixtures used in repair applications and existing hardened concrete are discussed.The bulk of the literature agrees that bond properties of SCC to embedded reinforcement, pre-stressing strands, and hardened concrete is higher than that of vibrated concrete (VC). The rheological properties of the SCC, including the yield

“…Literature shows extensive investigations on fresh and mechanical properties (compressive, splitting tensile, and flexural strengths as well as modulus of elasticity, shrinkage and bond strength) of SCC including their comparison with that of CVC (Soleymani Ashtiani et al, 2011, Soleymani Ashtiani et al, 2010, Desnerck et al, 2010, Valcuende et al, 2009, De Almeida Filho et al, 2008, Domone, 2006, Persson, 2001). In addition, researchers have been working on the structural performance in RC members cast with SCC under monotonic loads in the past few years (Hassan et al, 2008, Lachemi et al, 2005, Sonebi et al, 2003.…”

Seismic Performance of High-Strength Self-Compacting Concrete in Reinforced Concrete Beam-Column Joints

SUMMARY:Beam-column joints of reinforced concrete building frames play an important role under seismic excitations. These are one of the most congested areas in reinforced concrete framed structures; placement of concrete and proper compaction in such areas are hence substantially challenging. This offers a unique area of application for self-compacting concrete which can flow through every corner of extensively reinforced area without any vibration. Therefore if implementing self-compacting concrete in beam-column joints does not compromise seismic performance of the frame, it can be used instead of conventional concrete. This paper focuses on implementation of high-strength self-compacting concrete in beam-column joints and assessment of its seismic behaviour under reversed cyclic loading. Three interior beam-column subassemblies chosen to vary in concrete type and compressive strength are designed as per the New Zealand Standard NZ3101:2006. The specimens are instrumented to measure the load, displacement/drift, ductility, joint shear deformations, and elongation of the plastic hinge zone. The cracking pattern at different load levels and the mode of failure are also recorded and compared among different specimens.

“…However, this standard involves a cast-in-place procedure that requires shape modification of fibers, which will introduce manufacture complexity. Filho et al [16] have reported an alternated experiment layout for pull-out test, in which a rebar was penetrated into a cylindrical concrete matrix that was mounted on a load cell. Thus, mounting the specimen on a properly designed testing machine according to its shape and dimension would eliminate most of the complexity and will simplify the entire procedure.…”
