Influence of Recycled Aggregate Quality on Recycled Concrete

Abstract:

This article deals with the influence of recycled aggregate quality on recycled concrete. Replacement of natural aggregate by recycling aggregate has a negative influence on the properties of concrete. Three types of recycled aggregate were used for the production of concrete. The samples of recycled aggregate were obtained from two recycling plants in the Czech Republic. The samples of recycled aggregate were tested by pycnometric method. From the test results, a different quality of recycled aggregate was discovered. For the testing of concrete, a total of eight concrete mixtures were made, one of which was a reference mixture and the natural aggregate was replaced by recycled aggregate of varying ratio in the other mixtures. Finally, it is possible to say that use of recycled aggregate in concrete influences the properties of concrete. This influence depends on the quality and amount of recycled aggregate in the concrete.
