In this research paper an attempt has been made to utilize the recycled concrete in place of ordinary concrete for end use utilization in construction applications. Three different samples have been prepared by replacing basic concrete constituents through waste materials from demolished sites. The performance characteristic of recycled concrete has been compared with ordinary concrete. Compressive strength, flexural strength and water absorption rate has been compared for the samples of both the concrete. Slightly improvement in strength has been noticed at specified replacement proportion only, however it decrease mainly. It was observed that water absorption capacity of new concrete was higher than conventional concrete. Increased water absorption rates in new concrete raise durability concerns, especially in humid climates. Such type of replacement attempt may promote circular economy by improving sustainability, reducing waste output and conserving resources like aggregates and cement which further lead towards eco-friendly practices.

摘要

In this research paper an attempt has been made to utilize the recycled concrete in place of ordinary concrete for end use utilization in construction applications. Three different samples have been prepared by replacing basic concrete constituents through waste materials from demolished sites. The performance characteristic of recycled concrete has been compared with ordinary concrete. Compressive strength, flexural strength and water absorption rate has been compared for the samples of both the concrete. Slightly improvement in strength has been noticed at specified replacement proportion only, however it decrease mainly. It was observed that water absorption capacity of new concrete was higher than conventional concrete. Increased water absorption rates in new concrete raise durability concerns, especially in humid climates. Such type of replacement attempt may promote circular economy by improving sustainability, reducing waste output and conserving resources like aggregates and cement which further lead towards eco-friendly practices.
