Abstract
The use of recycled materials in concrete has drawn considerable attention in recent years as it means to enhance sustainability, strength, minimize landfill waste, cut carbon emissions and diminish the environmental influence of construction methods. This study focuses on investigating the compressive strength behaviour and sustainability analysis of rubberized concrete incorporating recycled aggregates. In this study, compressive strength tests have been conducted following standardized procedures to assess the load bearing capacity of rubberized concrete at different curing periods. The results will provide valuable information for engineers, researchers, and policymakers engaged in the development and utilization of sustainable construction practices. Recycle aggregates size ranging from 4.75 mm to 25 mm collected from crushing pile head from various construction site are utilized in this experimental research and also rubber crumbs are used as a partial substitute of fine aggregate at percentages of 6%,12%,18% and 25%, while maintaining a constant ratio of cement to water 0.45. The study was conducted at three different curing days of 7 days, 14 days and 28 days. From the test result, it has been noticed that conventional concrete has achieved the most effective result compared to the other percentages of mixtures of rubber crumb. Additionally, the compressive strength has been gradually decreased up to 56.82% in tandem with the increasing percentage of rubber crumb replacement in the specimens.
