Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel.
The third week of July is designated as "Ohio Aggregates and Industrial Minerals Awareness Week" in order to educate the public about, increase public awareness of, and recognize the important contributions of the state’s aggregates and industrial minerals industry to construction and transportation and to the state’s economic viability and to recognize the industry’s environmentally responsible stewardship of the state’s resources.
