A part of the Breccia category, it is characterized by angular fragments (clasts) of contrasting marbles cemented together.
Physical and Mechanical Properties
- Water Absorption:Typically ranges from 0.15% to 0.30%. This low water absorption rate makes it suitable for a variety of indoor applications without significant risk of water damage.
- Density:Approximately 2.68 – 2.71 g/cm³. This relatively high density translates to a sturdy and durable material.
- Flexural Strength:Ranges generally around 12 - 18 MPa. This property indicates its resistance to bending and is significant for structural uses.
- Compressive Strength:Generally lies between 110 - 130 MPa, reflecting its capability to withstand heavy loads.
- Hardness:Typically measures between 3 and 4 on the Mohs scale, indicating a moderate level of scratch resistance.
- Porosity:Low porosity level, typically around 0.3% to 0.5%, enhancing its resistance to staining and moisture penetration.
- Slip Resistance:Coefficient of friction is moderate, making it suitable for indoor flooring with proper finishes.
Chemical and Mineral Composition (% by weight)
- Calcite (CaCO3):Approximately 85% - 95%. The predominance of calcite contributes to its crystalline and translucent properties.
- Silica (SiO2):Roughly 2% - 5%. Silica contributes to the marble's hardness.
- Iron Oxides (Fe2O3):Around 1% - 3%. Provides the reddish-brown, amber, and taupe hues.
- Magnesium Carbonate (MgCO3):Approximately 1% - 2%, adds slightly to the color spectrum and durability.
Usage
