Description
Blanco Castilla Granite is a natural stone known for its aesthetic appeal and robust physical and mechanical properties. Quarried in El Berrueco, Sierra de Guadarrama, Madrid, Spain, this granite is characterized by its white to light-grey color with subtle grey, white, and occasional darker mineral speckles or accents. The typical granular crystalline nature of this medium-grained and compact granite contributes to its strength, durability, and relatively low water absorption.
Physical and Mechanical Properties:
- Water Absorption: 0.29% (weight %)
- Density: 2690 kg/m³
- Flexural Strength: 14.5 - 15 MPa
- Compressive Strength: 145 - 150 MPa
- Hardness: Comparable to other granites, typically around 6-7 on the Mohs scale
- Porosity: Low, contributing to its low water absorption and durability
- Slip Resistance: Dependent on surface finish, typically good with finishes like honed or flamed
Chemical and Mineral Compositions (% by weight):
While specific quantities may vary, typical granite compositions include:
- Quartz: 20-60%
- Feldspar: 10-65% (including both plagioclase and/or orthoclase)
- Mica: 5-15%
- Other Minerals: Includes smaller amounts of minerals such as biotite, amphibole, or magnetite which contribute to the darker speckles
Usage:
- Residential and Commercial Applications: Countertops, flooring, wall cladding, and staircases
- Outdoor Use: Paving, landscaping, and decorative features due to its durability and weather resistance
- Monuments and Sculptures: Its aesthetic and structural properties make it suitable for artistic and architectural projects
Maintenance:
- Routine Cleaning: Use pH-balanced cleaners to maintain surface appearance and integrity
- Sealing: Although granite is low-porosity, periodic sealing can help preserve its appearance and increase resistance to staining, especially for countertops
- Avoid Abrasives: Use non-abrasive cloths and tools to avoid scratching the surface
Surface Finish Options:
- Polished: Smooth, glossy finish that enhances color and pattern
- Honed: Smooth, matte finish with less reflectivity
- Flamed: Textured finish, achieved through thermal treatment, enhancing slip resistance
- Bush-Hammered: Rough texture providing a rustic appearance
- Leathered: Unique finish offering a tactile, soft texture with a muted sheen
Blanco Castilla Granite's combination of aesthetic qualities and robust physical and mechanical properties makes it a versatile choice for various architectural and design applications. Its maintenance-friendly nature further complements its use in both residential and commercial projects.
