In this study, prevention of scouring around bridge piers, used to form a fishway is applied to block of rivers occured corrosion, sometimes make significant reduction, in the life of the product due to the river's condition. Accordingly, rivers PC block by applying the GFRP Rebar with recycled aggregate was to enhance economy and increase durability.

This study is intended to assess the usability of recycled aggregate which is produced by wastes-concrete. It analyzes the quality of the recycled aggregate which is produced through the acid treatment process. The conclusions of the study are as follows. The absorption and the specific gravity of acid treated aggregates (both fine and coarse) was found much better than the ordinary recycled aggregates. The concrete made by incorporating acid treated aggregates exhibited higher compressive strength at all ages as compared to the concrete produced by using ordinary recycled aggregates.
