Aggregate is the component of a composite material that resists compressive stress and provides bulk to the material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. Aggregates are generally added to lower the amount of binders needed and to increase the strength of composite materials.
Sand and gravel are used as construction aggregate with cement to make concrete and increase its mechanical strength.[1] Aggregates make up 60-80% of the volume of concrete and 70-85% of the mass of concrete.[2]
