Impact strength of Hybrid Steel Mesh-and-Fiber Reinforced Cementitious Composites

Deflection Ductility of Slabs Made of Hybrid Mesh-And-Fibre-Reinforced Cementbased Composite

“…The maximum PO-Vf (%) adopted in this study is 2.5%, because the author experienced difficulties while mixing PO-Vf (%) of more than 2.5% in plain cement mortar, and, to further avoid workability related issues, PO-Vf (%) has been restricted to 2.5% for experimental purposes [10][11][12][13]24].…”

“…In order to improve the deflection ductility of ferrocement elements, previous studies [5,[9][10][11][12][13] have recommended that discontinuous fibres of a volume fraction of 0.5 to 2.5% (with a 0.5% interval) be added to the cementitious matrix of SMRCC. A new hybrid cementitious composite using mesh and fibre reinforcement in combined form have been suggested for improving strength and ductility performance by several authors [1], [6].…”

“…Deflection ductility of a structural element (slab, beam) is determined by experiments employing simple flexural tests [17][18] based on mid-span deflection [19][20][21]. Previous studies [1], [5], [10][11][12], [22][23] have shown that deflection ductility behavior is characterized by the ability to sustain higher levels of loading after the first cracking while undergoing a large deformation [17]. The deflection ductility at the first crack and the ultimate load bearable in cement-based composites depends upon element thickness, type of reinforcement (mesh and/ or fibres), and the volume fraction (percentage) of mesh and fibres [1], [10][11][12].…”

Combining mesh and fibres in thin cementitious composites will result in improved flexural ductility performance [1], [10][11][12], [18], [24][25]. Since a detailed study is needed to understand the flexural load-deflection behavior of thin slab elements reinforced with mesh and fibres and deflection ductility behavior [10][11][12], [18], the present study has made an attempt to combine steel mesh and polyolefin fibres as reinforcement in hybrid form and study its flexural deflection ductility.…”
