The Recycled aggregates properties may be different accordingly types of concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete. Aggregate recycling is a simple process there is no complex method involved. The recycling method includes breaking, removing, and crushing existing concrete into a material with a specified size and ...
However, finding a way to distinguish the different types of platelet aggregates could lead to better ways to diagnose or treat blood vessel-clogging diseases. To make this possible, Zhou, Yasumoto et al. have developed a method called the "intelligent platelet aggregate classifier" or iPAC for short.

Classification Of Aggregate Aggregate classification. The classification of Aggregate is generally based on their geological origin, size, shape, unit, weight, etc. Aggregate is the major ingredient of concrete. Aggregate is derived from rocks. They are broadly divided into two categories i.e. fine and coarse aggregates.

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller.This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate.
Classification of Aggregates Based on Size Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size
