Testing

Water Absorption:
0.2 - 0.4%
Density:
2660 - 2720 kg/m³
Flexural Strength:
13 - 14.5 MPa
Compressive Strength:
160 - 170 MPa
Stone texture:
a coarse- to medium-grained natural granite characterized by warm golden-yellow to beige base tones, often mixed with soft cream, light brown, and occasional grey mineral patches that create a natural, moderately varied appearance. The stone typically shows a subtle speckled and slightly cloudy crystalline pattern rather than strong veining, giving it a uniform yet naturally textured visual effect suitable for large-scale architectural use. In terms of texture and structure, it is a dense, interlocking crystalline rock composed mainly of quartz, feldspar, and minor mica minerals, forming a compact, durable, and highly resistant granite typical of Brazilian golden beige- cream yellow granite varieties, with good performance for both interior and exterior applications.

Description

Carajas Granite is a natural stone known for its distinctive and warm aesthetic appeal. Quarried in the region of Carajás, Pará, in northern Brazil, this granite displays a beautiful golden-yellow to beige base mixed with tones of soft cream, light brown, and occasional grey mineral patches. Its appearance is characterized by a subtle speckled and slightly cloudy crystalline pattern, providing a uniform yet naturally textured look.

Physical and Mechanical Properties:

  • Water Absorption:Typically low, around 0.2-0.4%, indicating good resistance to moisture penetration.
  • Density:Approximately 2,660 - 2,720 kg/m³, indicating a dense and solid composition.
  • Flexural Strength:Generally in the range of 13-14.5 MPa, showcasing good structural capacity for various applications.
  • Compressive Strength:Typically between 160-170 MPa, denoting its capability to withstand substantial loads.
  • Hardness:Comparable to 6-7 on the Mohs scale, reflecting its durability and resistance to scratching.
  • Porosity:Very low porosity, contributing to its stain resistance and longevity.
  • Slip Resistance:Slip resistance values can vary based on finish, but the stone generally provides a good traction surface, particularly when flamed or brushed.

Chemical and Mineral Composition (% by weight):

  • Quartz:Approximately 30-35%, contributing to its hardness and resistance.
  • Feldspar:Dominant mineral, comprising around 50-60%.
  • Mica (biotite, muscovite):Roughly 5-10%, imparting a characteristic shimmer and enhancing structural integrity.
  • Other Minerals (e.g., amphiboles, garnets):Combined make up around 5-10%, providing subtle color variations and patterns.

Usage and Applications:

  • Interior Applications:Ideal for countertops, flooring, wall cladding, fireplaces, and backsplashes in kitchens and bathrooms due to its aesthetic appeal and durability.

  • Exterior Applications:Suitable for facades, paving, and exterior wall cladding, thanks to its weather resistance and structural strength.

Maintenance:

  • Requires minimal maintenance; regular cleaning with mild detergent and water is typically sufficient.
  • Sealing is recommended periodically to enhance stain resistance, particularly for kitchen and bathroom surfaces.

Cutting Sizes (cm):

  • Customizable to project needs, but commonly available sizes include:
  • Slabs: 2 cm and 3 cm thicknesses, suitable for larger surfaces.
  • Tiles: 30x30, 40x40, 60x60 cm, popular for flooring and wall applications.

Available Common Surface Finish Options:

  • Polished:High-gloss finish that enhances color and textures, ideal for indoor applications.
  • Honed:Smooth, matte finish that offers a more subdued look, suitable for areas where glare needs to be minimized.
  • Flamed:Textured finish providing excellent slip resistance, suitable for exterior and wet areas like poolsides.
  • Brushed:Creates a slightly textured, soft finish, suitable for both interior and exterior applications where a rustic appearance is desired.
  • Leathered:A tactile finish that adds a sense of depth and sophistication without high sheen.
