agregades

Aggregates are granular materials used in construction and other industries. They are typically composed of a mixture of sand, gravel, and crushed stone. Aggregates are essential components of many construction materials, including concrete, asphalt, and mortar. The properties of aggregates, such as their size, shape, and composition, can significantly influence the performance of the final product.

In concrete production, aggregates make up a large portion of the volume, providing bulk and structural integrity. They also contribute to the strength, durability, and workability of the concrete. The type and grading of aggregates used are carefully selected to achieve desired concrete properties for specific applications, such as pavements, buildings, and bridges.

Asphalt mixtures, used for road surfaces and other paved areas, also rely heavily on aggregates. Aggregates in asphalt act as the skeleton, providing the load-bearing capacity and resistance to deformation. The aggregate gradation in asphalt is crucial for achieving a dense, stable, and durable pavement surface.

Beyond concrete and asphalt, aggregates find applications in drainage systems, landscaping, and as a base or sub-base material for roads and railways. The availability and cost-effectiveness of aggregates make them a fundamental resource in the construction sector worldwide. Various testing methods are employed to characterize aggregates and ensure they meet industry standards and project specifications.
