Manufactured Sand

Manufactured sand is a construction material produced by crushing or grinding, screening, and classifying rock or gravel to meet specifications set forth by ASTM, Federal and State highway departments, and the U.S. Army Corps of Engineers. The demand for economical and efficient sand producing crusherry has grown as natural sand deposits diminish.

Concrete – Manufactured sand produced in a Gyradisc crusher is preferred because the cubical particle shape not only contributes more strength to the concrete, but results in further savings because less cement is required. Independent tests have proved that the more cubical the aggregate and the lower the proportion or flaky and elongated particles, the more acceptable the material will be from the mix design aspect. Natural sands have a tendency to have rounded corners and consequently produce a concrete which is not quite as strong as concrete using manufactured sand.

Asphalt – Gyradisc manufactured sand produces a stronger and more stable mixture for asphalt because of the interlocking of angular aggregate particles, while the surface of the cubical crushed particle provides greater area for the volume occupied than the round particle. This permits cementing the particles together with asphalt and reduces the possibility of displacement.
