PROPERTIES OF RECYCLED AGGREGATE CONCRETE

In terms of morphological characteristics, recycled aggregate is less favorable than natural aggregate. The grains are irregular, mostly with angular shape, rough and with cracked surface and porous. These grain characteristics grains significantly affect the workability of fresh concrete, as well as the permeability of liquids and gases in the hardened state; they also significantly depend on the
