It is generally accepted that when natural sand is used, up to 30 percent of natural crushed coarse aggregate can be replaced with coarse recycled aggregate without significantly affecting any of the mechanical properties of the concrete.

Uncrushed gravel or stone which is the result of natural disintegration and crushed gravel or stone are usually called the "Coarse Aggregates". As mentioned earlier, coarse aggregates are stones that are retained on sieve.

Natural Sand– it is the aggregate resulting from the natural disintegration of rock and which has been deposited by streams or glacial agencies Crushed Stone Sand – it is the fine aggregate produced by crushing hard stone.

The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes contain both angular and round particles. The coarse aggregate particles are usually crushed stone or crushed gravel, and the fine aggregate particles are usually natural sand.

Both coarse aggregates (particle sizes of 20 mm to 4 mm) and fine aggregates (particle sizes less than 4 mm) are required but the proportions of different sizes of coarse aggregate will vary depending on the particular mix required for each individual end use.

Natural landscaping stone is rounded gravel that is perfect to use anywhere mulch would be used, on pathways, or to accent driveways. Crushed stone is more uniform in color than natural stone, ideal in flower beds or as a decorative driveway stone.
