Classification of Aggregates Based on Size and Shape

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. Fine aggregate

Aggregate (composite) Wikipedia

Most composites are filled with particles whose aspect ratio lies somewhere between oriented filaments and spherical aggregates. A good compromise is chopped fiber, where the performance of filament or cloth is traded off in favor of more aggregate-like processing techniques. Ellipsoid and plate-shaped aggregates are also used.

The original rock mined in the form of blasting, etc., is coarsely crushed and finely crushed by a crushing machine, and then divided into finished aggregates of different sizes using a vibrating screen.

Section III: Surface Gravel

Gravel is made up of three groups of aggregate: stone, sand,and fines. Depending on what the material is to be used for, the ideal blend of these three groups varies greatly. For example, good surface material for a gravel road would need more material passing a #200 sieve than a good base material.

The production of aggregates involves a relatively simple process of surface mining, crushing, sizing and, frequently, washing which requires large volumes of fresh water. Chemicals are not used in the processing of aggregates although minor quantities of a flocculent, or similar agent, may be used in removing sediments from process wash water.

Four different type of coarse aggregate was used. These aggregates were selected as flat, elongated, spherical and mixed shape. The shape properties were determined by digital image processing with two different views of aggregates. In this sense, the three dimensions of aggregate, the areas and perimeters of the views were determined.
