“…The strength may not be palpable at an early age due to the dilution effect of GGBFS in place of cement since the reactivity of GGBFS is very slow compared to Portland cement. This could be due to the low density of the C-S-H gel formed by the GGBFS particles in the hydration reaction or the unavailability of free calcium hydroxide for the pozzolanic response [5,8,9,11,12,19,26].…”

“…The 30% GGBFS substitution and 3.77% reinforcement volume fraction in ferrocement showed better performance in loaddeflection behavior, first crack load, ultimate load, energy absorption, and ductility ratio than other specimens. Jaraullah et al [19] investigated the properties of mortar containing GGBFS and Metakaolin (MK) on ferrocement. The utilization of GGBFS and MK provided good mortar performance.…”

A reinforced mortar type that can be created with a relatively thin thickness is ferrocement. Using ferrocement as a mechanically sound and sustainable building material has produced several benefits, including less use of raw materials, decreased accumulation of waste materials, and reduced greenhouse gas emissions. Cement as a constituent material of ferrocement is an environmentally unfriendly material; therefore, a more environmentally friendly cement replacement material is needed, namely Ground Granulated Blast Furnace Slag (GGBFS). Thus, creating sustainable (green) fertilizers is the main goal of this work. There are three primary stages to experimental work: Using slag cement (GGBFS) in place of partial cement of 0%, 10%, 20%, and 30% is the initial step. The primary reinforcement in the second level is wire-welded mesh, with volume fractions of support (Vf) of 1.2%, 1.8%, and 2.4%. During the final phase, a maximum of three different test objects were tested for compressive strength, water penetration depth, and flexure at a 28-day age. According to the findings, employing GGBFS led to good mortar performance. According to studies on mortar, the percentage of GGBFS utilized in a work may be determined by comparing the GGBFS substitution rates of 10%, 20%, and 30%, which show no differences in tendency. The test findings did not considerably improve the bending strength and cracking behavior of ferrocement reinforced with wire-welded mesh. One of them is influenced by the age of the concrete; at 28 days, the added material GGBFS has not yet reached its maximum strength, which results in a negligible improvement in bending strength and cracking behavior.

“…The consumption of hundreds of tons of tires annually is a result of a wide spread of cars, which calls for efficient disposal of these used tires, recycling the of these used tires, and extracting the wires that are used to strengthen the structural properties of ferrocement, which are characterized by high tensile resistance, this study has emphasized the creation of environmentally friendly (green) ferrocement slabs [1][2][3]. So that it is cheap, environmentally friendly and, available, which will contribute to reducing the cost of strengthening and rehabilitating concrete structures [4,5].…”

Ferrocement is extensively utilized in construction as a structural material, given its exceptional mechanical properties and impact strength. This study aimed to analyze the performance of ferrocement that is reinforced with recycled steel wire tires under static loads. This current study a comparative investigation of behavior of compressive strength of ferrocement cubes and flexural behavior of ferrocement panels and behavior of ferrocement panels reinforced with tire Steel wire tires under static loads. Ferrocement slabs sample was (L 500×W 500× t 50mm) in size, and 15 slabs were subjected to static point load. The number of wire mesh layers, which was replaced by recycling tire steel wire as a ratio of the volume of wire mesh, was the main parameter in the current study. The percentage of recycle steel wire tires are 33% and 66% and 99% from of steel wire mesh for reinforcements of ferrocement panels. The results presented, the behavior of panels under static load at ultimate failure and first crack. It showed that ferrocement have 99.0% steel wire tires gave a good performance under static loading which were required to increase the load value to make the first crack and ultimate failure, and causing late of the failure and less deflection.

“…Shear fasteners help in distributing the impact load across the panel’s surface, preventing concentrated stress and reducing the risk of fracture and puncture. Jaraullah et al 13 investigated the static and impact properties of ferrocement panels using green waste chemicals, and studies have shown that good performance can be achieved with metakaolin, GGBS, and limestone powder in mortars. In addition, the rupture modulus of ferrocement panels reinforced with a 3 mm diameter welded wire grid increased by 75% compared to 2 mm diameter welded wire grid-reinforced ferrocement panels with a fiber content of 0.6%.…”

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.
