Technical Data Sheet: Gray Emperador Marble

Gray Emperador is a sophisticated natural stone characterized by its rich gray tones and delicate white-to-light-gray veining. It is highly valued in architectural projects for its durability and aesthetic versatility.

Below is the technical specification breakdown based on standardized laboratory testing.

Physical and Mechanical Properties

Property Value Unit
Hardness 3 – 4 Mohs
Unit Volume Weight 2.71 – 2.73 g/cm3
Density (Specific Gravity) 2.73 – 2.75 g/cm3
Water Absorption (Atmospheric) 0.15 – 0.25 % (by weight)
Water Absorption (Atmospheric) 0.40 – 0.60 % (by volume)
Water Absorption (Boiling Water) 0.25 – 0.35 % (by weight)
Water Absorption (Boiling Water) 0.70 – 0.85 % (by volume)
Porosity 0.50 – 0.80 %
Compressive Strength 80 – 110 MPa (N/mm2)
Compressive Strength (After Freezing) 75 – 95 MPa (N/mm2)
Strength to Blow (Impact Resistance) 10 – 15 kgf . cm/cm3
Strength to Bending (Flexural) 10 – 18 MPa (N/mm2)
Ratio of Fullness (Solidness) 99.2 – 99.5 %
Degree of Pores 0.5 – 0.8 %
Average Abrasion Strength 15 – 20 cm3/50 cm2

General Observations

  • Durability: Due to its high Ratio of Fullness and low Porosity, Gray Emperador exhibits excellent resistance to environmental wear, making it suitable for high-traffic flooring.
  • Freeze-Thaw Resistance: The minimal loss in Compressive Strength after Freezing indicates that this marble can be used in exterior applications in temperate climates, provided it is sealed correctly.
  • Maintenance: With a Mohs Hardness of 3-4, it is a typical calcitic marble. It is susceptible to etching by acidic substances and should be treated with high-quality penetrative sealers to maintain its finish.

Note: These values are averages based on standard quarry samples. Natural stone is subject to geological variation; therefore, specific batch testing is recommended for large-scale structural projects.
