A Study on the Mechanical Properties of Concrete using Crumb Rubber in Replacement of Fine Aggregate

Abstract

One of the most popular building materials, concrete is always being researched to improve its mechanical
qualities and sustainability. This study looks at whether it's possible to substitute some of the fine aggregate used in the manufacturing of concrete with crumb rubber, a recycled material made from used tyres. The objective is to
evaluate how the addition of crumb rubber affects the mechanical characteristics of concrete, including its tensile,
flexural, and compressive strengths. This research explores using crumb rubber from discarded tires as a sustainable alternative to fine aggregate in concrete production. The project systematically investigates various crumb rubber sizes and concentrations, comparing them with control mixtures. Testing includes material characterization, mechanical assessments, and durability evaluations under different conditions. The study aims to provide valuable insights into crumb rubber's potential to enhance concrete's mechanical properties while reducing environmental impact. The investigation's results provide significant insights into the field of sustainable building materials. While concurrently addressing the environmental issues related to the disposal of scrap tyres knowledge of crumb rubber's capacity to improve or modify the mechanical qualities of concrete might result in creative uses in the building industry. The findings are expected to benefit construction professionals, researchers, and policymakers seeking eco-friendly solutions in the construction industry, promoting a greener future for concrete production.
