When it comes to construction, aggregates are an essential component. Depending on grain size, these materials can be divided into two categories: fine and coarse-grained. Fine aggregates, such as sand, are used to fill the void created when coarse-grained aggregates are combined. This is also the type of aggregate used to fill sand traps on golf courses.
The strength of concrete depends largely on the selection of aggregates. This selection process involves various tests to check the stability of the material. Factors such as shape, size, texture and other properties are taken into account when choosing an aggregate for a concrete mix. Aggregates can be further classified based on their source.
Natural aggregates come from natural sources, while manufactured aggregates are produced in factories. Additionally, aggregates can be divided into three categories based on their bulk specific gravity: lightweight, normal weight and heavy weight. The classification of aggregates is based on a variety of characteristics, including shape, size and origin. At General Kinematics, we understand that proper sorting of aggregates by color is essential for successful construction projects.
