Which type of aggregate is typically sourced from natural deposits?

Natural aggregate is sourced directly from the earth's crust and consists of materials such as sand, gravel, and crushed stone that occur in nature. This type of aggregate is often used in construction and concrete production because it is readily available and meets the necessary specifications for various applications. Natural aggregates are extracted through mining or quarrying, making them distinct from other types, like manufactured, processed, or recycled aggregates.

Manufactured aggregate, on the other hand, is created from industrial processes, typically involving the crushing and screening of materials like concrete or stone. Processed aggregate refers to materials that have undergone treatment to enhance their properties, and recycled aggregate is derived from the reprocessing of previously used materials, such as repurposed concrete from demolished structures. Therefore, while each type of aggregate has its own source and production method, natural aggregate stands out as it is directly obtained from natural deposits.
