Evaluate the Use of Recycled Aggregate in Concrete

摘要

Recycling is a key component of modern waste reduction. The application of recycled aggregate has been started in many construction projects in Australia, America and other Asian countries. This research is an attempt to study the basic properties of recycled aggregate. The properties of the recycled aggregate were also compared with natural aggregates. Additionally, the properties of recycled aggregate.Concrete were also determined and explained here. Concrete cylinders were cast at different replacement of fresh aggregate such as 20%, 40%, 60% and 80%. A total of 45 concrete cylinders of standard size were produced comp rising of 36 cylinders with recycled aggregate and 9 cylinder with fresh aggregates. The basic concrete properties were determined. The compressive strength, UPV and Rebound Hammer test were performed at the age of 7, 14 and 28 day s. Furthermore, the recycled aggregate concrete cylinders properties were also compared with the fresh aggregate concrete cylinders specimen’s properties.
