[0002] Recycled concrete is made by crushing, cleaning, and grading discarded concrete blocks, mixing them with a specific proportion and grading, and then adding cement and water to partially or completely replace natural aggregates such as sand and gravel (primarily coarse aggregate). Recycled concrete can be made using the following aggregate combinations: all recycled aggregate; coarse aggregate is recycled aggregate and fine aggregate is natural sand; coarse aggregate is natural crushed stone or pebbles and fine aggregate is recycled aggregate; or recycled aggregate replaces part of the coarse or fine aggregate.
