2570 - 2640 kg/m³
Flexural Strength:
7.75 - 10.2 MPa
Compressive Strength:
95.94 - 142.0 MPa
Stone texture:
a two-mica monzogranite with a medium-grained, slightly porphyritic crystalline texture, composed of tightly interlocking mineral crystals that produce a dense, compact structure with fine visual depth and durability; dominant medium-grey background with subtle tonal variations ranging from light grey to slightly darker grey shades. The surface typically displays a balanced distribution of darker mineral grains and lighter crystalline flecks, occasionally including white, black, or faint beige particles that create a refined salt-and-pepper visual effect.
