Testing
- Water Absorption:
- 0.15 By weight %
- Density:
- 2632 kg/m³
- Flexural Strength:
- 11.80 MPa
- Compressive Strength:
- 133.5 - 149.8 MPa
- Stone texture:
- a coarse-grained, intrusive igneous stone characterized by a warm pink to reddish overall appearance, created primarily by abundant feldspar crystals that impart a soft rosy tone across the surface, often blended with greyish-white backgrounds and scattered black mineral specks or darker veins that add visual depth and variation; its pattern is generally homogeneous yet subtly dynamic, with occasional porphyritic features where larger feldspar crystals stand out within a granular matrix. In terms of texture and structure, it exhibits a phaneritic, granular and hypidiomorphic composition, typical of durable granites, with a well-balanced mineral mix of quartz, microcline, plagioclase, and biotite, resulting in a dense, hard, and compact stone with a consistent, directionless structure and low porosity, making it suitable for both interior and exterior architectural applications.
Description
Rosa Arronches Granite is a coarse-grained, intrusive igneous stone characterized by a warm pink to reddish appearance, primarily due to abundant feldspar crystals that impart a soft rosy tone. It often features a blend of greyish-white backgrounds and scattered black mineral specks or darker veins, adding visual depth and variation. The pattern is generally homogeneous, yet subtly dynamic, occasionally exhibiting porphyritic characteristics where larger feldspar crystals are evident within a granular matrix. The texture and structure of this granite are phaneritic, granular, and hypidiomorphic, common to durable granites, characterized by a dense, hard, and compact composition with low porosity and a consistent, directionless structure. It is sourced from Herdade das Pinas in Arronches, Portalegre, Portugal.

- Flexural Strength: 11.80 MPa
- Compressive Strength: 133.5 - 149.8 MPa
- Hardness: High, suitable for extensive wear
- Porosity: Low
- Slip Resistance: Moderate, depending on finish
Mineral Compositions (% by weight):
- Quartz: 20%
- Microcline: 40%
- Plagioclase: 30%
- Biotite Mica: 8%
- Others: 2%
Usage:
- Exterior Applications: Cladding, pavers, curbing, and facades due to its durability and aesthetic appeal.
- Interior Applications: Flooring, countertops, vanity tops, fireplace surrounds, and wall cladding.
Maintenance:
- Regular cleaning with pH-neutral cleaners.
- Sealing recommended, particularly in high-use areas, to prevent staining and improve longevity.
- Avoid harsh chemicals or abrasive cleaners that may damage the surface or reduce its sheen.
Available Common Surface Finish Options:
- Polished: Highlights the glossy, reflective quality of the stone.
- Honed: Offers a smooth, matte finish without reflection.
- Flamed: Provides a rough texture, increasing slip resistance.
- Bush-hammered: Yields a rugged surface, also enhancing slip resistance for exterior uses.
- Leathered: Provides a soft, textured finish that is both tactilely pleasing and visually interesting.
Rosa Arronches Granite is an excellent choice for both traditional and contemporary architectural projects, offering an appealing aesthetic along with the robust physical properties typical of quality granite.
