“…and/or fibres, the higher the flexural load (or equivalent flexural strength) of HMFRCBC slab elements [41]. In a similar study, Abushawashi and Vimonsatit (2014) [42] used hybrid PVA fibre and steel wire mesh in fibrous ferrocement slab panels measuring 620 × 200 × 25 mm (thickness) with MVr=0.80% (3 mesh layers) and PVA Vf=1.5%, which showed first crack and ultimate deflection of 0.57 mm and 10.38 mm, respectively.…”

Steel Mesh-Reinforced Cementitious Composites (SMRCC) (traditionally known as ferrocement) have been in existence for few decades, but have some limitations set on element thickness and number of reinforcing mesh layers and the resulting deflection ductility. Therefore, the author has made an attempt to explore whether deflection ductility will improve in mesh-reinforced cementitious composites (25 mm thick) if discontinuous fibres are added to slab elements. were analyzed. From the flexural load-deflection curves it has been observed that HMFRCBC slabs demonstrate higher flexural load-carrying capacity and deflection ductility when compared to SMRCC slabs. This study shows that higher the polyolefin fibre volume fraction (PO-FVf) from 0.5 to 2.5% (with a 0.5% interval) in HMFRCBC slabs, the higher the flexural deflection ductility. The Deflection Ductility Index (DDI) of HMFRCBC (with 5 layers of mesh and PO-FVf=2.5%) is 4.5 times that of SMRCC. This study recommends that HMFRCBC can be used as an innovative construction material due to its higher flexural ductility characteristics.

“…The ductility ratio for ferrocement slabs tested under flexure showed the highest value of 1.77 in the case of F4MB1PPF-S and the least value of 1.16 for F1MC1PPF-S. The trend is increasing by increasing the percentage volume fraction (V r ) of reinforcement mesh [ 36 ]. Therefore, the presence of PPF inhibits intrinsic cracking in concrete.…”

“…The increased number of wire meshes distributed along the thickness of the slab resulted in more strength capacity and ductile behavior [ 34 ]. The optimization of the reinforcement wire contentled to a general increase in the flexural strength, ductility, tensile strength and energy dissipation capabilities [ 35 , 36 , 37 , 38 ]. The experimental results also concluded that 0.6% of superplasticizer along with 20% fly ash and 5% SF resulted in improved flexural performance in strength and toughness [ 39 ]…”

Reinforced concrete structures, particularly in cold areas, experience early deterioration due to steel corrosion. Fiber-Reinforced Concrete (FRC) is an emerging construction material and cost-effective substitute for conventional concrete to enhance the durability and resistance against crack development. This article examines the structural performance of hybrid ferro fiber reinforced concrete slabs (mix ratio of mortar 1:2) comprising silica fume, layers of spot-welded mesh and different ratios of polypropylene fibers. The ferrocement slabs are compared with a conventional Reinforced Cement Concrete (RCC) slab (mix ratio of 1:2:4). The experimental work comprised a total of 13 one-way slabs, one control specimen and three groups of ferrocement slabs divided based on different percentages of Poly Propylene Fibers (PPF) corresponding to 0.10%, 0.30% and 0.50% dosage in each group. Furthermore, in each group, the percentage of steel ratio in ferrocement slabs varied between 25% and 100% of the steel area in the reinforced concrete control slab specimen. For evaluating the structural performance, the observation of deflection, stress-strain behavior, cracking load and energy absorption are critical parameters assessed using LVDTs and strain gauges. At the same time, the slabs were tested in flexure mode with third point loading. The experimental results showed that the first cracking load and ultimate deflection for fibrous specimens with 0.5% fiber and 10% silica fume increased by 15.25% and 13.2% compared with the reference RCC control slab. Therefore, by increasing the percentage of PPF and steel wire mesh reinforcement in the ferrocement slab, the post-cracking behavior in terms of deflection properties and energy absorption capacity was substantially enhanced compared to the RCC control slab.
