What is meant by "aggregate blending"?

The concept of "aggregate blending" refers to the process of combining different types and sizes of aggregates to achieve specific performance characteristics that are required for the intended application. This process is crucial because aggregates have varying properties, such as size, shape, texture, and absorption rates, which can greatly influence the performance of the final mixture. By carefully selecting and blending aggregates, technicians can enhance the mixture's workability, durability, strength, and other desired attributes.

Blending aggregates enables the customization of the material to meet specific engineering requirements or to comply with certain standards. This might involve adjusting the proportions of coarse and fine aggregates or mixing different materials to achieve optimum strength and performance in concrete or asphalt applications, ultimately contributing to the longevity and effectiveness of the construction project.
