Evaluate the Effect of Acid Attack on Partial Replacement of Crumb Rubber with Coarse Aggregate

Abstract

Implementing an experimental investigation on partial replacement of crumb rubber with coarse aggregate is the main objective of this project.

Methods: For a very long time, research was being done to find alternatives to disposing of waste tyres. Rubber from waste tyres can be recycled, which is one of these alternatives. The most common method is to use rubber from recycled tyres. Due to its energy absorption, low weight, elasticity, and properties, sound and heat insulation, recycled tyre rubber is a promising construction material. In this study, waste tyre rubber from recycled tyres was utilized to replacing the coarse aggregates by weights of 1.5% and 3%.

Findings: Due to having much greater compressive strengths than regular concrete, according to the findings, the concrete made from waste tyre rubber failed in a plastic, ductile manner rather than a brittle failure. In this nominal scale is compared with replacing the coarse aggregates by weights of 1.5% and 3%.  So compared with nominal scale, 1.5% and 3% will give effective outcome.

Novelty: In this study, they used crumb rubber to replace coarse aggregate in normal concrete of grade M25 to identify the compressive strengths of the concretes.
