cost of recycled coarse aggregate per unit

Use of recycled aggregates for low carbon and cost ...

2018-7-10  The coarse recycled aggregate (RA) and recycled washed glass sand (RGS), meeting the requirements of BS EN 12620, were used in RAC mixes to substitute natural aggregates by 25% on mass basis. RA was graded 20-5 mm aggregates and observed to be irregular shaped compared to natural coarse aggregates.
