What is 6aa Crushed Limestone?

Crushed limestone is a fundamental construction aggregate derived from sedimentary rock. The designation ‘6aa’ pertains to a specific grading standard used in some regions, often indicating a fine aggregate with a maximum particle size around 4.75mm (passing a No. 4 sieve), similar to ‘6a’ grading. This fine size makes it exceptionally useful for applications requiring excellent compaction, smooth surface finishes, and as a binder component. The primary mineral content is calcium carbonate (CaCO3), providing good strength, durability, and chemical stability for construction purposes. The angular shape of the crushed particles promotes interlocking, creating dense and stable layers when properly compacted.

The consistent grading of 6aa crushed limestone ensures predictable performance, making it a reliable material for demanding applications in Lille’s dynamic construction environment. It is frequently utilized in binder courses for asphalt pavements, as a base material for interlocking pavers, and as a key ingredient in specific concrete mixes. Maiyam Group is committed to supplying this essential aggregate, ensuring it meets the rigorous specifications mandated by French and EU construction authorities, thereby supporting the region’s infrastructure development.

Grading and Particle Size

The grading of 6aa crushed limestone is its defining feature, placing it within the fine aggregate category. Particles typically pass a 4.75mm sieve (No. 4 sieve). This fine size allows it to efficiently fill voids between larger aggregates and create a smooth, dense surface upon compaction. The controlled crushing and screening processes ensure a high proportion of particles fall within this specified range. The angularity of these small fragments enhances their ability to interlock, contributing to superior compaction and stability, which is crucial for pavement and foundation layers.

For construction projects in Lille, where durability and performance are paramount, the fine grading of 6aa limestone is highly beneficial. It provides a stable bedding layer for pavers, prevents unwanted voids in asphalt, and can be used in decorative concrete applications. Its compactability ensures a solid foundation that can withstand moderate traffic and environmental stresses. Maiyam Group guarantees that its 6aa crushed limestone adheres to precise grading specifications required by French construction norms, offering reliability for various applications in the Hauts-de-France region.

Chemical Composition and Properties

Composed primarily of calcium carbonate, 6aa crushed limestone exhibits moderate hardness and good resistance to weathering, making it suitable for diverse construction environments. Its chemical stability ensures longevity in typical applications. The material’s density, generally ranging from 1400 to 1700 kg/m³, contributes to its compactability and load-bearing capabilities when used appropriately. The high surface area due to its fine particle size can influence its behavior in composite materials like asphalt and concrete, affecting workability and final material properties.

When sourced and processed under strict quality controls, 6aa crushed limestone offers a consistent and dependable material. Maiyam Group upholds ethical sourcing practices and rigorous quality assurance protocols, ensuring that the limestone supplied complies with international trade standards and environmental regulations. This dedication guarantees a high-quality product essential for demanding construction projects in Northern France.

Types of 6aa Crushed Limestone

While ‘6aa crushed limestone’ generally denotes a fine aggregate size, variations exist based on the degree of screening and the quantity of ultra-fine particles (dust), influencing its specific applications in Lille.

• Type 1: Clean 6aa Crushed Limestone: This variant contains minimal dust or ultra-fine particles. It might be specified for certain concrete mixes where precise aggregate control is needed or in applications where some minimal void space for drainage is desired, though it’s less common for pure drainage.
• Type 2: 6aa Limestone Screenings (with fines): This is the most prevalent type, containing a significant proportion of fines. These fines act as a natural binder, allowing the material to compact into an extremely dense, hard, and smooth surface. It is the preferred choice for paver bases, pathway toppings, and as a binder course in asphalt mixes, commonly specified for projects in Lille.
• Type 3: Blended 6aa Aggregate: In specialized scenarios, 6aa limestone may be blended with other aggregate sizes or materials to achieve unique performance characteristics required for specific engineered applications, such as specialized bedding or fill materials.
• Type 4: Decorative 6aa Limestone Applications: While primarily a functional aggregate, finely screened 6aa limestone can sometimes be used in decorative concrete finishes or specific landscaping contexts where a fine stone mulch is desired for aesthetic appeal.
