What is typically included in the classification of aggregates?

The classification of aggregates encompasses various characteristics that define their properties and usability in construction. When considering geological origin, it refers to the type of rock or mineral from which the aggregate is derived, such as granite, limestone, or gravel. This characteristic can significantly impact the strength, durability, and overall performance of the aggregates in concrete or asphalt mixes.

Shape and size distribution are equally vital in the classification process. The physical dimensions and form of the aggregates influence how they pack together and their surface area, which affects the bond with cement or asphalt. Size distribution ensures that different sizes of aggregates are present in the mix, which can help in achieving optimal strength and stability.

By combining both geological origin and the shape and size distribution of aggregates, a comprehensive classification system is achieved, allowing for deeper insights into how these materials will behave in various applications. Thus, recognizing the significance of both these aspects is essential for understanding the overall classification of aggregates.
