Assessment of the mechanical attributes via mathematical simulations for distinct sizes of morsel rubber

Rubber waste is a significant environmental and health problem worldwide, resulting from the non-biodegradability of rubber products and increasing rubber production. The primary sources of rubber waste include discarded tires and waste generated during the production of rubber products. Environmental pollution and health risks result from the improper disposal of rubber waste, which includes burning and dumping in landfills. Rubber waste as a replacement for sand in concrete has gained attention in recent years due to the growing problem of rubber waste and the environmental benefits of reducing sand consumption. This research aims to see the variation in concrete properties by using distinct particle sizes of rubber waste as a partial replacement for sand in concrete. An experimental result has been produced by substituting morsel rubber waste particles for fine aggregates in concrete in amounts ranging from 0% to 10% while adding 2.5% to the standard concrete's strength benchmarks. The concrete with and without Bakelite plastic waste as aggregates was observed in the compressive, abrasion, impact energy, water absorption, water permeability, and microstructural properties tests, displaying good strengths. After strength parameters were examined, the most robust concrete was produced using fly ash-based concrete with a 7.5% BPW content. The addition of rubber waste can improve the properties of concrete, such as reducing its weight and increasing its energy absorption capacity. However, using rubber waste in concrete has some limitations, such as lowering compressive strength.
