A Study on the application of the fine recycled concrete aggregate in the PHC piles

Along with recent improvement of recycling technique, the quality of the recycled concrete aggregate have become very competitive to the natural concrete aggregate. Therefore, a practical use of the recycled concrete aggregate may be possible for structural members. Majority studies about the recycled concrete aggregate was emphasized a limitation of fundamental study concerned with a strength characteristics and durability of the recycled aggregate concrete. Therefore, for the extension of application of recycled concrete aggregate, this investigation verifies the strength characteristics and structural performances of PHC piles used with coarce and fine recycled concrete aggregate.
