Aggregates in Concrete | Construction Aggregate Supplier - CEMEX USA
CEMEX offers a wide variety of aggregate for concrete and construction to suit our customers’ needs:
Crushed Stone and Manufactured Sand
These products are obtained by mining rock and breaking it down to a preferred size. In the case of manufactured sand, the product is obtained by crushing rock to the selected shape or texture, ensuring product and project specifications are met. Sources of crushed stone can be igneous, sedimentary, or metamorphic.
Gravel deposits are produced through a natural process of weathering and erosion. The resulting aggregate for concrete can be used in roads, manufacturing, or decorative purposes.
Sand occurs naturally and is composed of fine rock material and mineral particles. Its composition is variable depending on the source. It can be used for roads, for aggregate concrete manufacturing, or sanitation.
Recycled concrete is created by breaking, removing, and crushing existing concrete to a preferred size. It is commonly used as a base layer for other construction materials because it compacts to form a firm surface.
Aggregates are obtained from natural sand or sand-and-gravel pits, hard-rock quarries, dredging submerged deposits, or mining underground sediments. For more information about how aggregates are extracted, view our process »
