“…A promising approach to reducing inorganic solid waste has recently emerged: using solid waste as an alternative concrete aggregate. Waste rubber tires from old vehicles are a type of inorganic waste [1]. Similarly, organic waste like coconut shells can be utilised as an aggregate in concrete.…”

Concrete is the most widely used artificial material worldwide, and its production depends on the availability of components like sand, granite, and cement. The prices of these materials have significantly increased in recent years. This study investigates the effect of using coconut shells (12mm – 16 mm) as the coarse aggregate and rubber (4.75 mm) as the fine aggregate in concrete. The concrete was intended to achieve compressive strength of 40 N/mm2, with coarse aggregate replacing coconut shells and fine aggregate replacing rubber at 5%, 10%, and 15% by weight. According to the study, 5% is the optimum amount of coconut shell to replace coarse aggregate with. The optimal replacement percentage of fine aggregate with rubber is 5%. Therefore, tests will be conducted on all of the aforementioned samples to determine their different characteristics, including compressive strength, split tensile strength, RCPT test, and sorptivity test.

Utilizing waste byproducts from mining industries and recycled rubber as alternate materials in railway tracks promotes sustainability of transportation infrastructure, while also increasing track longevity by reducing ballast degradation. This paper provides an overview of two such applications including (i) rubber-intermixed ballast stratum (RIBS) by replacing 10% ballast aggregates with granulated rubber particles with the particle sizes carefully selected according to Australian Standards, (ii) synthetic energy absorbing layer using a mixture of steel furnace slag, coal wash and rubber crumbs to replace traditional capping layer. These materials when tested using large-scale triaxial apparatus and field trials proved that tracks with waste materials performed better than the conventional ballasted tracks by reducing ballast breakage and exploiting the higher damping potential of these materials. Though the vertical deformations of the track slightly increased by using these materials albeit within the specified standards, the overall stability improved by reduced dilation and track vibrations. Increasing the life of ballast layer can lead to long-term cost benefits by saving millions of dollars in track maintenance and provide environment benefits through minimizing quarrying of natural rock aggregates and reducing the carbon footprint of mining industries.

Waste tires have emerged as a severe environmental threat worldwide as they create a number of disposal and landfill burden issues. In the present study, environmental pollutant crump rubber derived from waste discarded tires was reinforced with epoxy resin and prepared by means of an open-mold casting method to assess its mechanical properties. The impact of crump rubber content (0, 10, 20 and 30 vol.%) on the mechanical behavior of the composites was assessed using three-point bending tests at a constant strain rate of 0.1 and 0.01 mm/s. The stress–strain profiles of the 0.01 mm/s specimens revealed higher strains to failure compared with the 0.1 mm/s tested specimens and all the specimens showed brittle failure. Irrespective of the strain rates, tests revealed a marginal increase in the strength values of the composites and a significant increase in the modulus of all the composites compared with neat epoxy specimens. The results suggest that crump rubber can be effectively used in utilitarian composites requiring good flexural modulus and strength properties. Crump rubber epoxy composites with 30 vol.% of crump rubber showed higher modulus and strength compared with neat epoxy and other composites owing to the toughening phase induced by the crump rubber particles. The failure and fracture features of the specimens were analyzed using scanning electron microscopy.
