Nero Port Saint Laurent Marble Blocks for Quarry Projects
Nero Port Saint Laurent Marble Blocks are natural marble blocks selected from selected black marble quarry resources. The block material shows deep black, charcoal, white vein movement and occasional grey mineral clouds and contrasting white vein lines across a dark marble ground. With density around 2.60 - 2.74 g/cm3, water absorption < 0.45% and compressive strength 85 - 135 MPa, it is suitable for gangsaw slab production, luxury wall slabs, floor slabs, stair panels and cut-to-size.
Category: Marble Blocks
Color: Black
Product description
Nero Port Saint Laurent Marble Blocks are natural marble blocks prepared for quarry block trading, gangsaw slab production and architectural stone processing. The selected material is associated with selected black marble quarry resources; blocks are inspected for compact body, dramatic veining and export block integrity. It presents deep black, charcoal, white vein movement and occasional grey mineral clouds, giving buyers a clear marble block character rather than granite, limestone, travertine, artificial stone or thin slab material.
The block body has dense calcite marble body with bold white veining and natural quarry-cut block faces. Its visual layout is defined by contrasting white vein lines across a dark marble ground. Each block should be inspected for cracks, soundness, usable cutting direction and color continuity before gangsaw production.
Marble blocks are commonly processed into slabs, tiles, stair panels, wall cladding pieces and cut-to-size project stone. Nero Port Saint Laurent Marble Blocks are recommended for gangsaw slab production, luxury wall slabs, floor slabs, stair panels and cut-to-size architectural projects. Sealing and suitable handling are advised after slab cutting, especially for wet-zone and high-contact applications.
Category: Natural Marble Blocks
Color: deep black, charcoal, white vein movement and occasional grey mineral clouds; natural marble block lots may show vein, shade and quarry-face differences.
Surface Condition: Rough quarry block / sawn block faces / wire-sawn faces / irregular quarry edges
Product Form: Natural Marble Blocks
Texture: dense calcite marble body with bold white veining and natural quarry-cut block faces.
Density: 2.60 - 2.74 g/cm3 (stable compactness for block handling and slab processing)
Water Absorption: < 0.45% (final slabs should be sealed according to finish and application)
Compressive Strength: 85 - 135 MPa (suitable for conventional marble block processing)
Block Processing Suitability: suitable for gangsaw cutting, trimming, resin treatment when needed, calibration and polished / honed / brushed slab finishing.
GANGSAW SUITABILITY
Nero Port Saint Laurent Marble Blocks raw blocks are compatible with standard gangsaw processing equipment for slab cutting. The block should be positioned according to vein direction and checked for open cracks before cutting. Stable quarry block geometry helps improve slab recovery and reduce waste during trimming.
Recommended Processing: Gangsaw slabs (1.8 cm & 2 cm), followed by resin reinforcement when required, calibration, edge trimming and honed / polished / brushed surface treatment
Expected Slab Yield: Approximately 76-86 slabs per block (based on 1.8 cm thickness)
Polish Result: The final slab surface should be inspected under project lighting to confirm color, vein visibility, filling quality and batch consistency.
