“…The improved impact resistance and reduced damage make ferrocement panels with wire mesh and SF a viable option for use in structures such as partition walls, footbridges, roof shells, silos, swimming pools, and manhole covers subject to repeated impacts. (7) As the number of reinforcement layers increased, there was a noticeable reduction in the number of fragments that flew out from the back face of the specimens. This suggested that there were fewer and shorter cracks, possibly due to the stronger bond between the fibers and mortar matrix as the distance from the center of the contact zone increased and energy intensity decreased.…”

“…The researchers came to the conclusion that the use of wire can increase the life of the structure, improve its performance, and lower the need for repairs and replacement costs because ferrocement has a high tensile strength and is durable, making it an ideal material for the repair and maintenance of existing structures. Numerous studies have recently concentrated on the bending characteristics of ferrocement panels composed of cement mortar and wire mesh. − Memon et al examined the impact of ferrocement panels’ flexural strength and the possibilities for employing waste materials such as fly ash and ground granulated blast furnace slag as a partial replacement for cement up to 60% in the production of ferrocement. This strategy maintains the product’s strength and durability while offering benefits, including waste recycling, resource conservation, and lower production costs.…”

The primary objective of this experimental study is to examine the response and energy absorption capacity of ferrocement panels exposed to low-and high-velocity impact loads. The panels are reinforced with two different types of mesh layers, namely, welded wire grid (WWG) and expanded wire grid (EWG), with varying percentages of steel fibers (SF). The ferrocement panel system is made up of cement mortar reinforced with 0−2% SF with an increment of 1% and wire grid layers arranged in three different layers 1, 2, and 3. A consistent water−cement ratio (w/c) of 0.4 is maintained during mortar preparation, and all panels are subjected to a 28-day curing process in water. The study utilized square-shaped ferrocement panels measuring 290 mm × 290 mm × 50 mm. The panels are exposed to repeated impact blows from a 2.5 kg falling mass dropped from a height of 0.80 m. The count of blows necessary to commence the first crack formation and the cause of ultimate failure are recorded for each panel. The study reports that an increase in SF content and the number of wire grid layers increased the number of blows needed for both the first crack and the ultimate failure. In the high-velocity impact test, 7.62 mm bullets are fired at the panels from a distance of 10 m with a striking velocity of 715 m/s. The study observed and analyzed the extent of spalling, scabbing, and perforation. The results showed that an increase in fiber content and the number of wire grid layers led to a decrease in the area of scabbing and spalling compared with the control specimens. It was also possible to see the mode of failure and crack pattern for impacts with low and high velocities.
