Flexural Strength (MPa): ~10-15 MPa.

Abrasion Resistance: High, making it suitable for high-traffic areas.

Density (g/cm³): ~2.4-2.6 g/cm³ (moderate density, easy to work with).

Water Absorption (%): ~0.5-1.5% (low porosity, resistant to moisture).

Chemical Composition (%):

Calcium Carbonate (CaCO?): ~95-98% (primary component).

Magnesium Carbonate (MgCO?): ~1-2%.

Silica (SiO?): ~0.5-1%.

Iron Oxide (Fe?O?): ~0.1-0.5% (contributes to the warm beige hue).

Other Trace Minerals: <1%.

Mineral Composition:

Calcite: ~95-98%.

Dolomite: ~1-2%.

Quartz: ~0.5-1%.
