Testing

Water Absorption:
less than 0.2%
Density:
2710 - 2770 kg/m³
Flexural Strength:
15 - 17 MPa
Compressive Strength:
190 - 210 MPa
Stone texture:
a deep, consistent black to very dark gray background, often appearing almost uniform at first glance, with very fine crystalline mineral speckling that becomes subtly visible under polished or reflective finishes. Its overall appearance is clean, minimal, and highly elegant, with little variation, making it especially suitable for modern architectural designs where a solid dark tone is preferred. The texture is dense, fine- to medium-grained, and composed of tightly interlocking quartz and feldspar crystals, giving the stone excellent compactness, high hardness, and low porosity

Description

Preto Ceara Granite is a luxurious, deep black to very dark gray granite known for its sophisticated appearance and superior physical properties. Quarried primarily in Brazil, this granite is widely used in modern architectural designs that demand a sleek and minimalistic aesthetic.

Physical and Mechanical Properties

  • Water Absorption: Typically low, often less than 0.2%, indicating excellent resistance to water infiltration.

  • Density: Ranges from 2,710 to 2,770 kg/m³, ensuring a dense and robust structure.

  • Flexural Strength: Generally falls between 15 to 17 MPa, providing good resistance to bending and tension.

  • Compressive Strength: High compressive strength ranging from 190 to 210 MPa, making it very durable under pressure.

  • Hardness: On the Mohs scale, it ranges around 6-7, indicating good scratch resistance.

  • Porosity: Very low, usually less than 1%, which enhances its durability and resistance to staining.

  • Slip Resistance: Varies based on finish; polished finishes have lower slip resistance compared to honed or textured finishes.

Chemical and Mineral Composition

  • Quartz: Approximately 20-30%
  • Feldspar (Plagioclase and Alkali feldspar): 50-60%
  • Biotite and Amphiboles: 10-20%
  • Other trace minerals: including oxides and accessory minerals, contributing to its color and physical properties.

Usage

  • Interior Applications: Ideal for countertops, flooring, wall cladding, and decorative elements due to its elegant appearance and durability.
  • Exterior Applications: Suitable for facades, outdoor flooring, and monuments. Its low porosity and high compressive strength make it resistant to weathering.

Maintenance

  • Routine Cleaning: Clean with a soft cloth and neutral pH detergent to avoid damage from acidic substances.
  • Sealing: Although its low porosity often means sealing is less frequently needed, applying a high-quality sealant can provide additional protection against stains.
  • Polishing: Periodically polishing the surface helps maintain its natural sheen and elegance.

Common Surface Finish Options

  • Polished: Achieves a high-gloss finish that enhances color and pattern but is less slip-resistant.
  • Honed: Provides a matte finish with better slip resistance for flooring.
  • Flamed: Achieved by heat-treating the surface to create a more textured, slip-resistant finish, suitable for exterior applications.
  • Bush-Hammered: Offers a rugged texture that is both visually appealing and slip-resistant.

Preto Ceara Granite's consistent color, fine-grained texture, and excellent mechanical properties make it a versatile choice for various architectural and design applications, providing both functional strength and aesthetic appeal.
