Understanding Crusher Stone: The Backbone of Construction

Crusher stone is produced by mechanically crushing large rocks, pedras, or quarry stones into smaller fragments of specific sizes. It’s categorized primarily by size (medido em milímetros), which determines its optimal application:

G1 (Curso Básico): Typically 37.5mm or larger. Used as a stable foundation layer under roads, edifícios, e calçadas.
G2 (Subbase): Around 19mm to 37.5mm. Provides drainage and support below G1 or directly under surfacing where heavy loads aren't primary.
G3 - G7 (Selected Layers/Drainage): Finer gradings (por exemplo, G5 ≈ 13.2mm max; G7 ≈ 9.5mm max). Used for sub-base layers requiring higher compaction (G5 is very common), bedding layers for pipes (G6/G7), drainage applications, and concrete production.
Crusher Sand/Dust: Fine material (75milímetros). Used for erosion control on riverbanks/dams ("rip rap"), gabion baskets filled with smaller stones (<250mm often called Gabion Stone).

The quality depends heavily on the source rock's geological properties – its hardness, durability against weathering ("weathering coefficient"),
