RESEARCH STUDY ON CLOSED RECYCLE OF HIGH STRENGTH PRESTRESSED CONCRETE POLE

Abstract

This paper describes the results of research study on closed recycle of high strength prestressed concrete pole. As the result, the main conclusions are as follows. 1) The quality of recycled coarse aggregate made from used concrete poles corresponds to the recycled aggregate class M. 2) The quality of recycled fine aggregate made from used concrete poles corresponds to the recycled aggregate class L. 3) There is a possibility that recycled aggregate made from used concrete pole can be applied for new concrete pole, if natural aggregate is replaced with a part of recycle aggregate.
