“…Recently, the influence of WRSF on the bending, tensile and post-cracking behavior of concrete was investigated, and the results revealed that the incorporation of WRSF enhanced the residual strength of concrete [24]. Utilizing waste tire crumb rubber and recovered coarse aggregate in concrete preparation contributes to the construction industry's long-term sustainability [25]. Furthermore, the research on the mechanical properties and durability of WRSF-reinforced CBCs has revealed that the addition of WRSF improved the impact resistance, shrinkage behavior and crack propagation of concrete compared to that of plain concrete [26][27][28][29].…”

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.

“…Se muestra que el concreto con caucho granulado tiene una durabilidad diferente con la temperatura ambiente de prueba y puede proporcionar una referencia para la aplicación del concreto de caucho granulado en la penetración de iones anti cloruro. (Shahjalal et al, 2020), en su estudio están buscando formas de reducir y reutilizar estos materiales de desecho provenientes de neumáticos para promover una práctica de construcción sostenible y una de las formas es incorporar caucho fino proveniente de los neumáticos desechados y agregado grueso en la producción de concreto pertenece a un futuro sostenible de la industria de la construcción. Se encuentra que los valores de tenacidad y ductilidad aumentan para el contenido de caucho hasta un 5% y luego comienzan a disminuir para el 10% de caucho desmenuzado.…”

Los avances en la tecnología del concreto conducen a la búsqueda de materiales alternativos que brinden mejoras en las propiedades del concreto y al mismo tiempo colaboren con reducir la contaminación del medio ambiente. En este artículo se revisará las investigaciones publicadas en revistas científicas indexadas en la base de datos Scopus y SciencieDirect, que tienen como objetivo estudiar el uso del caucho de neumáticos triturados para la producción de concretos en general. Se discutirá las metodologías y técnicas de trituración de las partículas de los neumáticos, así como también se destacará los avances realizados con la incorporación de material en el concreto, centrándose en las propiedades del concreto modificado con caucho de neumáticos. En conclusión, se discutirán las recomendaciones para las futuras investigaciones y la aplicación del caucho de neumático en el concreto.

“…Many researches have been carried out with various types of fibres. The potentiality of coconut stem, coconut fibre, coconut and coconut fibre ash, banana fibre bars, steel fibre, crumb rubber and steel fibres, waste tires rubber and recycled aggregate, FRP rebar and steel fibre, polypropylene hybrid fibre to enhance the strength characteristics of concrete, was elaborately investigated and satisfactory result was found [1][2][3][4][5][6][7][8][9][10][11]. A research work to evaluate the effectiveness of banana fibre to promote the impact strength lightweight self-compacting concrete executed that 1.25% addition of banana fibres could improve the impact strength of lightweight self-compacting concrete with no undesirable effect on the self-compatibility [12].…”

The use of fibers in concrete at relatively low volume fraction has been gaining rising popularity among researchers for the recent years due to its availability, ability to enhance overall performance and cost effectiveness. Fibers are mainly classified according to their origin. Numerous researches have been carried out with natural and artificial fibers separately to elucidate its effect on the various parameters of concrete. However, a little finding is available about the comparative study among these three distinct types of fibers affecting concrete properties. In this study coconut coir, nylon thread and low-cost galvanized iron wire have been selected as natural, synthetic and steel fibers respectively. Coconut coir and nylon thread were mixed at three different percentage of 1.5%, 2.5% and 3.5% respectively by weight of cement. Steel fibre contents 1.5%, 2.5% and 3.5% respectively by weight of concrete. The results were obtained through an experimental investigation that shows the influence of natural, synthetic and steel fibers on rheological and mechanical properties of concrete. Optimum fibre content was 2.5% where steel fibre shows a maximum 17% and 30% rise in compressive and flexure strength respectively. On the other hand, fibres play a great role with its combining effect on the post cracking ductility and energy absorption of concrete.
