Recycled Aggregates—Profitable Resource Conservation Aggregates are Required for Construction Projects Aggregates are composed of rock fragments that may be used in their natural state or after mechanical processing such as crushing, washing, and sizing. Natural aggregates consist of both sand and gravel, and crushed stone.

Four different recycled aggregate concretes were produced; made with 50% of recycled coarse aggregates of four intensity levels. The damage of the recycled concrete is the bond failure of the interface of aggregate and mortar, which is basically the same as the damage process and damage mechanism of the natural concrete.
