The suitability of replacement of natural coarse aggregate with recycled coarse aggregate mainly ... more The suitability of replacement of natural coarse aggregate with recycled coarse aggregate mainly depends upon properties of recycled coarse aggregates. The presence of loose mortar particles and surface cracks results in inferior aggregate properties. This experimental study presents a surface treatment and an impregnation which enhance the properties of coursed recycled aggregates. In this study recycled aggregate were treated by soaking in hydrochloric acid (HCL) at 0.1M concentration and HCL treated recycled aggregate impregnated in silica fume solution. The basic properties of recycled aggregate before and after treatment and it effects on concrete were examined. The results show that the behavior of recycled coarse aggregate has improved after treatment. Usually there will be decrease in the strength value of recycled coarse aggregate concrete when compared with natural coarse aggregate concrete .the strength improvement can be achieved in a much better way by using treated recycled aggregate in concrete than untreated recycled aggregates.
