aggregate, structure, shape and size of grains, aggre-gate grading and so on. The resistance to crushing and abrasion of recycled aggregate is less than the respective resistan-ce of natural aggregate, which is a consequence of easier separation and crushing of the mortar layer around the recycled aggregate grains. In addition,
