A Comprehensive Review of Incorporating Steel Fibers of Waste Tires in Cement Composites and Its Applications

Abstract

Accumulating vast amounts of pollutants drives modern civilization toward sustainable development. Construction waste is one of the prominent issues impeding progress toward net-zero. Pollutants must be utilized in constructing civil engineering structures for a green ecosystem. On the other hand, large-scale production of industrial steel fibers (ISFs) causes significant damage to the goal of a sustainable environment. Recycled steel fibers (RSFs) from waste tires have been suggested to replace ISFs. This research critically examines RSF’s application in the mechanical properties’ improvement of concrete and mortar. A statistical analysis of dimensional parameters of RSFs, their properties, and their use in manufacturing various cement-based composites are given. Furthermore, comparative assessments are carried out among the improvements in compressive, split tensile, and flexural strengths of plain and RSF-incorporated concrete and mortar. In addition, the optimum contents of RSF for each strength property are also discussed. The influence of RSFs parameters on various strength properties of concrete and mortars is discussed. The possible applications of RSF for various civil engineering structures are reviewed. The limitations and errors noticed in previous review papers are also outlined. It is found that the maximum enhancement in compressive strength (CS), split tensile strength (STS), and flexure strength (FS) are 78%, 149%, and 157%, respectively, with the addition of RSF into concrete. RSF increased cement mortars’ CS, STS, and FS by 46%, 50.6%, and 69%, respectively. The current study encourages the building sector to use RSFs for sustainable concrete.

Sustainability Enhancement through High-Dose Recycled Tire Steel Fibers in Concrete: Experimental Insights and Practical Applications

“…The RSF performs equally to the ISF in improving concrete split and flexure strengths, according to a previous study [28,29]. A comprehensive review by Zia et al [30] further supports the potential use of RSFs in cement composites, highlighting significant enhancements in mechanical strengths.…”

Evaluating the effectiveness of waste glass powder for the compressive strength improvement of cement mortar using experimental and machine learning methods

“…Numerous approaches have been utilized by academics to enhance the efficiency of cementitious composites [ [11] , [12] , [13] , [14] , [15] , [16] ]. Also, to produce eco-friendly materials, waste materials might be incorporated as replacements for aggregate [ [17] , [18] , [19] ], cement [ 20 , 21 ], and reinforcing fibers [ [22] , [23] , [24] , [25] , [26] , [27] , [28] ]. The use of recycled aggregate concrete and fiber-reinforced recycled aggregate concrete is gaining popularity [ 29 , 30 ].…”

The Effect of Superabsorbent Polymers on Mechanical Characteristics and Cracking Susceptibility of Alkali-Activated Mortars Containing Ground Granulated Blast-Furnace Slag and Copper Slag

“…It also avoids contamination of the natural environment, depletion of natural resources and reduced capacity of final waste disposal arrangements [6,7]. Many alternative materials have been successfully used as a PC replacement, such as fly ash [8], blast-furnace slag [9], silica fume [10], ceramic waste powder [7], coal bottom ash and waste glass sludge [11], tires waste [12], rice husk ash [13], sugarcane bagasse ash sand [14], iron ore tailings [15], water treatment plant sludge [16], among others. This paper is focused on ground granulated blast-furnace slag (GGBS) and less popular, copper slag (CS) [5,17,18].…”
