In the construction industry, what does the term "aggregate" refer to?

The term "aggregate" in the construction industry specifically refers to materials like sand, gravel, or crushed stone that are used in the production of concrete and asphalt. These materials serve as the raw components that provide bulk and strength to the mixture. When combined with cement and water, aggregates improve the overall durability and stability of the construction material.

Understanding the role of aggregates is crucial in construction, as they make up a significant portion of concrete mixes and affect the properties and quality of the final product. Choosing the right type of aggregate is essential for achieving the desired strength, workability, and longevity of structures.
