Testing

Water Absorption:
0.20 %
Density:
2570 kg/m³
Flexural Strength:
7.75 - 10.2 MPa
Compressive Strength:
95.94 - 142.0 MPa
Stone texture:
a predominantly medium to dark grey background with natural tonal variations ranging from light grey to deeper graphite shades Two micas monzogranite. The stone typically presents a balanced salt-and-pepper appearance, created by the even distribution of darker biotite minerals and lighter quartz and feldspar crystals, occasionally accompanied by subtle white or black mineral flecks that add visual depth while maintaining a consistent overall look. In some slabs, faint crystalline clusters or soft micro-variations may appear, giving the stone a refined yet natural character suitable for large architectural surfaces. Structurally, Gris Conquistador Granite is petrographically classified as a two-mica monzogranite with a medium-grained, slightly porphyritic crystalline texture, composed of tightly interlocking mineral grains that form a dense, compact structure typical of Spanish granites, providing both visual uniformity and excellent durability.

Description

Gris Conquistador Granite is a charming natural stone characterized by its medium to dark grey background, enriched with natural tonal variations from light grey to deeper graphite shades. The granite features a balanced salt-and-pepper appearance due to the even distribution of darker biotite minerals and lighter quartz and feldspar crystals. Additional subtle white or black mineral flecks add depth while maintaining a consistent overall look. In some slabs, faint crystalline clusters or soft micro-variations enhance the stone's refined yet natural character, making it ideal for extensive architectural surfaces.

Structurally, Gris Conquistador Granite is a two-mica monzogranite with a medium-grained, slightly porphyritic crystalline texture.
