A Comprehensive Review on the Utilization of Recycled Waste Fibers in Cement-Based Composites

Abstract

Ecological problems such as natural resource depletion and massive quantities of waste for disposal are now guiding progressive civilization towards sustainable construction. The reduction of natural resources and the discarding of debris into open landfills are the two main environmental concerns. As a result, managing these solid wastes is a major challenge worldwide. In comparison to disposal, insufficient landfills, ecological degradation and the economic load on the relevant agencies, recycling and reusing waste materials have a considerable influence. Waste fiber has been studied for use as a cement-based composite (CBC) ingredient. Recycling waste fibers not only makes the cement composite more cost-effective and long-lasting but also helps to reduce pollution. Plastics, carpets and steels are among the various types of waste fibers reviewed in this study for their applications in cement-based materials. The mechanical properties of CBCs with different kinds of recycled-waste fibers were explored, including their compressive, flexural and splitting tensile strength and durability properties. The use of recycled fibers in the construction industry can help to ensure sustainability from environmental, economic and social standpoints. As a result, additional scientific research is needed, as well as guidance for more researchers and experts in the construction sector to examine the unknown sustainability paths. The barriers to the effective implementation of waste fiber recycling techniques in the construction sector were reviewed, and various solutions were proposed to stimulate and ensure their use in CBCs. It was concluded that CBCs containing recycled fibers provide a long-term and cost-effective alternative for dealing with waste materials.

Application of Cement-Based Carbon Fiber Material in Construction of Building Durability

“…However, due to the frequent agglomeration of carbon fiber materials, it is difficult to disperse in cement-based composite materials, studies have shown that adding dispersants or using ultrasonic technology can make them have better dispersibility in solution. Various studies have shown that doping carbon fiber materials into cement-based composites can effectively reduce or improve the electrical conductivity of their surfaces, in order to adapt to various environmental needs, and enhance its tensile strength and flexural strength [ 4 , 5 ].…”

Fabrication of Textile Waste Fibers Aerogels with Excellent Oil/Organic Solvent Adsorption and Thermal Properties

“…Therefore, an environmentally benign disposal process to upcycle and recycle textile wastes is necessarily required to alleviate potential health, fossil energy and environmental issues. Textile waste materials have applications in the production of ethanol [ 15 ], glucose [ 11 ], nanocellulose and cellulose nanocrystals, microcrystalline cellulose [ 16 ], biogas [ 17 ], thermal and sound insulation materials [ 18 ], cement and bricks [ 3 , 19 , 20 ] and polymer composites [ 21 ], and so forth. The traditional treatment method of textile waste has complicated procedures or low economic value.…”

Thermal performance characterization of cement-based lightweight blocks incorporating textile waste

“…Due to the periodic generation of TW, its reuse and recycling are considered promising in fulfilling the concept of circular economy [21]. A In this context, adding this type of wastes as building materials components can be a promising solution, contributing to the reduction of energy consumption employed in the exploitation of natural resources, performing a significant role in sustainability, including the environmental, economic, and social perspectives [22,23]. However, according to the literature review, few studies have been developed in this field, justifying more research work, namely with emphasis on obtaining building materials with thermal insulation capacity by incorporating TW.…”
