The classification of aggregates based on shape and size, as coarse-grained and fine aggregates are. Depending on grain size, aggregates are classified into two types. Fine aggregates are used in concrete as a filling material to fill voids. Coarse-grated aggregates are used in concrete to develop element strength.
Size is one of the most important parts of classifying an aggregate. Typically, the size of the aggregate is divided between fine and coarse-grained selections. Fine aggregates, such as sand, are used to fill the void created when coarse-grained aggregates are combined. Fine aggregate is also used to fill sand traps on golf courses.
Aggregates with sharp angular shapes with maximum voids ranging from 38 to 40% are called angular aggregates. Sorting aggregates by touch can help achieve that goal by classifying the material by the way it feels. Whether you need aggregates to form a subbase for foundations or pavements, decorative aggregates for driveways and paths, or just need something to fill in the unsightly holes, you need to know what type of aggregates will work best. The classification of aggregates is based on their shape, size, origin, and many other characteristics.
The aggregates are then engaged in quality testing, if it is safe to use them in concrete or other construction activity. The shape of the aggregates chosen will have a significant effect on the workability of the concrete. As a team with decades of experience, General Kinematics understands that proper aggregates classification can sometimes mean the difference between success and catastrophe. Determining the shape of an aggregate can be particularly difficult, since most aggregates are obtained by shot peening or grinding.
Coarse-grained aggregates are manufactured in different sizes, such as 10 mm, 12 mm, 20 mm, and manufactured sand is now also available instead of river sand. Aggregates form an essential part of many construction projects, from large-scale commercial works to smaller domestic works. Thanks to the wide range of colors of the aggregates, when properly classified, they can give their color to concrete products of any shape. Aggregates purchased in batches from a reputable supplier can have a uniform shape, if needed, but you can also mix aggregate forms if needed.
Due to the natural geothermal activity of the & weathering process, aggregates are produced from these types of rocks. Construction professionals easily understand the importance of correctly sorting aggregates by color. That said, it is always necessary to classify the aggregate by shape, since the shape of the aggregate will affect the viability of the concrete. Due to its angularity, it easily interconnects with other aggregates & fewer voids are formed in the concrete.
