“…Using aluminum fiber in concrete also leads to an improvement in the concrete properties, an increase in compressive strength, and a better enhancement in the structural behavior. Previous studies show that aluminum fiber content of 0.2% is able to increase the characteristics of strength, deformation, and energy of a concrete, while excess aluminum fiber reduces the original performance due to agglomeration and other factors [4][5][6][7][8][9]. Other than aluminum fiber, steel fiber, carbon fiber, and organic fiber are also common to be incorporated to improve the performance of a concrete [10][11][12].…”

Utilizing recycled waste as an additional construction material is an innovation that can reduce the negative environmental impacts caused by waste. One of the wastes that can be utilized in this case is aluminum cans. The use of aluminum fiber in concrete mixtures is appropriate since aluminum is resistant to corrosion or rust. This research aims to determine the effect of adding aluminum fiber on the compressive strength of concrete. The aluminum cans were shaved into fibers with dimensions of 2 x 35 mm. The resulting aluminum fiber is then added into the concrete mixture with a percentage of 0%, 0.05%, 0.075%, 0.1%, and 0.125% of the total volume of the test objects. Tests for compressive strength was then carried out after test specimens were aged for 28 days. The test results showed a peak compressive strength of (20.72 ± 0.35) MPa is observed at the addition of 0.05% aluminum fiber relative to the volume of concrete used for testing. A regression analysis was performed based on the relationship between the amount of aluminum fiber additive and the resulting compressive strength. Based on this analysis, the optimum value for aluminum fiber to be added to the concrete is 0.040% of its volume.

“…Design of experiments (DoE) has been a common technique gleaned from the statistical exploration of outcomes required to guarantee that well-founded results are obtained with little resources, time, and labour [20,21]. It helps make an empirical model with appropriate considerations and conforming responses, limiting experiment numbers, and testing the parameter interrelationships [22].…”

Performance Evaluation of Fiber-reinforced Ferroconcrete using Response Surface Methodology

Fibre-reinforced ferroconcrete is a new-generation type of concrete that has been found to have adequate performance. Global emissions of CO2 as a result of concrete production have damaged the earth's atmosphere. These emissions, together with construction waste, such as ceramic powder and aluminium waste, are considered one of the most harmful wastes to the environment, eventually leading to pollution. In this study, the fibre-reinforced ferroconcrete (FRFC) contained waste aluminium fibre, cement, ceramic waste powder, corrugated wire mesh, and fine and coarse aggregate. The cement content in the concrete mix was partially replaced with Ceramic Powder (CP) in proportions of 0%, 10%, and 20%, while the Aluminum Fibers (AF) were added in proportions 0, 1, and 2% to the concrete mix. The variation of ceramic powder and aluminium fibres was done using the central composite design of Response Surface Methodology (RSM) to create experimental design points meant to improve the fibre-reinforced ferroconcrete's mechanical performance. The results conclude that the mechanical performance of the FRFC was slightly improved more than conventional concrete, where at 20% replacement of ceramic powder and 1% addition of aluminium fibre to the concrete mix. There was more compressive, flexural, and split tensile strength increase than conventional concrete, with control concrete having strengths of 13.060, 5.720, and 3.110 N/mm2 and ferroconcrete 15.88, 6.68, and 3.83 N/mm2 respectively. This was further confirmed with microstructural images. The RSM model, with parameters such as; contour plots, analysis of variance, and optimisation, was used to effectively predict and optimise the responses of the ferroconcrete based on the independent variables (Aluminum fibre and Ceramic Powder) considered. The results of the predicted data show a straight-line linear progression as the coefficient of determination (R2) tends to 1, indicating that the RSM model is suitable for predicting the response of the variables on the FRFC.

“…On the other hand, chips resulting from the machining of steel parts are used as reinforcement [23]. At the same time, the inclusion of aluminum scrap can fibers in concrete improves the mechanical properties of the composite [24]. Steel fibers made from recycled materials can protect the environment and decrease pollution.…”

Experimental Characterization of a Functionally Graded Composite Using Recycled Steel Fiber

Many industries have recently focused on cost-effective materials with good mechanical properties. Steel fiber reinforced cementitious composites have proven their mechanical performance in industrial and structural components. The concept of recycled fiber-reinforced FGM is used as an alternative construction material, which can be one of the proposed cost-effective solutions. To achieve these objectives, an experimental program has been developed. A cementitious composite based on local materials was strengthened in two designs; one strengthened over the entire cross-section and the other strengthened only in the tensile zone. We also substituted a functional gradient material reinforced with recycled fibers considering the following volume fractions: 0, 0.5, 1, and 1.5%. This paper investigates the feasibility of using recycled fibers from industrial waste from steel wool manufacturing as reinforcement. We also characterized their mechanical properties using ultrasonic pulse velocity, compressive strength, flexural tensile strength, and shear strength. The results show that the corrugated recycled fibers are the ideal choice to increase the mechanical performance of the reinforced composite, including the improvement of flexural and shear behaviors. Therefore, the investigated FGC could be a valuable tool to optimize the design process in various structural applications and make the production of mechanically and environmentally economical composites possible.
