Sustainability in construction: RSF fibers and their use in structural mortars and concretes

The construction sector is therefore under increasing degree of pressure to adopt more sustainable methods of construction due to the enormous environmental impact brought forth by the traditional methods of concrete production: high CO₂ emissions; resource depletion; and excessive raw material extraction. Recycled steel fibers (RSFs), which provide potential solutions to these problems, are increasingly accepted as an eco-friendly alternative to enhance the performance of structural mortars and concrete. Being derived out of waste materials, RSFs are potential eco-friendly alternatives to conventional reinforcement methods, thus contributing to a Fiber-Reinforced Concrete (FRC) mix having less environmental footprint (the concept of using fibers from end-of-life tires illustrates how very important it is to recycle some items and the advantage they can impart in civil engineering). Also, on the other side, their application in civil engineering not only solves waste management problems but also enhances sustainability and performance attributes of structural materials. Further, with the development of new answers for environmental choices with cost benefits, this procedure sets the stage for a much more resilient and green construction industry.
