The Aggregate Manufacturing Process General Kinematics

The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 percent of concrete consists of both coarse and fine aggregates. If the aggregates are not properly sized, as well as clean and free from other matter, the concrete could fail to meet its desired strength and cause ...

Aggregate (composite) - Wikipedia

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
