Aggregates for Concrete. The proper selection of aggregates for use in concrete mixtures is critical to long term concrete performance. Aggregates generally occupy 60% to 75% of the concrete volume and strongly influence the concrete’s fresh and hardened properties, mixture proportions, and economy.
Concrete Materials offers the highest quality selection of rock, sand and gravel. We wash and grade many of our aggregate products to meet appropriate specifications.

Concrete is one of the worlds most used and strongest material. Concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates.
Mar 08, 2018· Aggregate. Definition: granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blastfurnace slag, used with a cementing medium to produce either concrete or mortar.
Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines ...
