“…[11][12][13] The extensive review of previous literature exhibited that matrix of ECC mainly consists of polymeric fibers such as polyvinyl alcohol (PVA fiber), polyethylene fiber (PE), polypropylene fiber (PP). [14][15][16] The parameters of ECC revealed that it is an ideal material for plastic hinge of beam-column connections. However, the economic aspect and scarcity of PVA and PE fiber limit the wider usage of ECC in structural concrete projects.…”

The present research examines the structural performance of exterior beam‐column connections made with the hybrid use of fibers and stone waste in engineered cementitious composite (ECC). The polyvinyl alcohol (PVA), recron 3 s polyester (PET) and micro steel fiber (MSE) were dispersed in various ECC mixtures to analyze the impact of fiber hybridization. The stone waste (SW) was utilized in different ECC mixtures as replacement of silica sand (SS). The performance of ECC beam‐column connection specimens was judged in terms of hysteresis load–deflection behavior, energy dissipation, ductility, and cracking pattern. The recorded results of ECC reinforced specimens were compared with specimens made with normal concrete (NC). Recorded results revealed that the connections made with ECCs exhibited better performance in terms of ductility and various parameters as compared to NC connections. The hybrid dispersion of fibers and addition of SW also contributed in improving the behavior of ECC specimens. The higher deformation, loading response, energy dissipation and ductility indicated that structures made with ECC can withstand strong ground earthquake motions.

“…Engineered cementitious composite (ECC) is the novel class of high-performance fiber reinforced cementitious material (HPFRCM), which can be used to overcome above mentioned requirements. The most superb characteristics of ECC is the high energy absorption capacity (equal to 30 KJ/m 2 ), high tensile strain capacity (1%-8%) and controlled crack width (< 100 µm) (Singh et al, 2019 a ;Li et al, 1998 a ;Singh et al, 2019 b ;Li et al, 1998 b ;Said et al, 2015;Sahmaran et al, 2009). Design of ECC rely on the theory of microcracks and fracture mechanics and it presents a strain hardening behavior with multiple tiny cracks (Sahmaran et al, 2009;Ranade et al, 2014;Li et al, 1994).…”

The addition of supplementary cementitious materials and fiber plays an important role in the mechanical and durability performance of ECC matrix. In the present research work, the assessment of the performance of ECC matrix with the utilization of iron industry waste and microfibers has been done. Three types of microfibers, i.e., polyvinyl alcohol (PVA) fiber, polyester (PET) fiber, and microsteel (MSE) fiber, were used at various percentages in hybridization to prepare total seven mixes. First, PVA was switched by PET fiber at dosages 5%, 10%, 15%, 20%,and 25% and afterwards another 25% by MSE fiber. The performance of various matrix proportions was judged based on the flexural response, electrical resistivity, air permeability, and sorptivity characteristics to introduce sustainable and cost effective ECC matrix. Test results revealed that hybridization of fibers enhanced the flexural and durability performance of ECC and also produced a cost effective and sustainable ECC matrix.

“…Coarse aggregates are excluded as they affect the distinct ductile nature of cementitious composite. The regular concrete and fiber reinforced concrete (FRC) undergoes brittle and strain softening failure, whereas ECC exhibits strain hardening behaviour with multiple micro cracks [7,8]. ECC is a wacky branch of FRC, which consists of different types of short length polymeric fibers.…”

Mortar based engineered cementitious composite (ECC) demonstrate strain hardening behaviour with multiple micro-cracks under tension. The distinctive behaviour of ECC, makes it ductile as compared to brittle nature of conventional concrete. Ductile nature of ECC, makes it applicable in seismic resistant, repairing and retrofitting areas and blast resistant structural elements. In the present investigation, two types of polymer fibers (i.e. polyester (PET) fiber and polyvinyl alcohol (PVA) fiber) have been used in hybridization with different percentages (2+0), (2+0.5), (1.75+0.5), (1.5+0.5) for making ECC. Also fly ash, 55% of the total cementitious material, has been used for making sustainable concrete. The compressive, flexural and tensile tests were performed to evaluate the mechanical behaviour of hybrid fiber reinforced cementitious matrix. The test results revealed that PET fiber and PVA fiber in combination enhanced the strength properties of ECC by bridging effect of hybrid fibers.
