Description

Kota Black Limestone is a high-quality natural stone quarried in the Kota district of Rajasthan, India. It is renowned for its distinctive, deep charcoal-to-black color and elegant appearance. Below are the detailed descriptions and properties of Kota Black Limestone:

Physical and Mechanical Properties:

  • Water Absorption:Typically less than 1.0% to 1.5%, indicating low porosity and good resistance to water-related damage.
  • Density:Approximately 2,500 to 2,600 kg/m³, reflecting its solid and dense nature.
  • Flexural Strength:Usually ranges from 14 to 18 MPa, suggesting good resistance to bending or transverse stresses.
  • Compressive Strength:Generally between 110 to 160 MPa, which ensures it can withstand significant loads or pressure.
  • Hardness:Falls between 3 to 4 on the Mohs scale, indicating moderate scratch resistance.
  • Porosity:Low porosity due to its dense composition, contributing to its durability and reduced water absorption.
  • Slip Resistance:Provides good slip resistance, especially when honed or flamed, making it suitable for flooring in wet areas.

Chemical and Mineral Compositions:

  • Calcium Carbonate (CaCO3):Dominant mineral, making up approximately 50% to 55% by weight.
  • Magnesium Carbonate (MgCO3):Comprises about 30% to 35% by weight, indicative of its dolomitic nature.
  • Silica (SiO2):Presence of about 5% to 8% by weight.
  • Alumina, Iron Oxide, and Other Minerals:Typically less than 5% combined, contributing trace amounts to its coloration and properties.

  • Interior Use:Flooring, wall cladding, countertops, staircases, and decorative elements due to its aesthetic appeal.
  • Exterior Use:Patios, pool surrounds, pathways, and driveways owing to its durability and weather resistance.

Maintenance:

  • Sealing:Can be sealed to preserve its dark tones or left unsealed to develop a natural patina over time.

  • Cleaning:Regular sweeping and occasional mopping with a non-acidic cleaner are recommended to maintain its appearance.

Cutting Sizes (cm):

  • Typically available in tiles and slabs of various sizes such as:
  • 30x30, 30x60, 60x60, and custom sizes as per project requirements.

Available Surface Finish Options:

  • Honed:Smooth, matte finish for a modern look suitable for interiors.
  • Polished:High-gloss finish enhancing color and providing a sleek appearance.
  • Brushed:Textured finish for a rustic appeal, offering increased slip resistance.
  • Flamed:Rough surface with excellent slip resistance, ideal for exterior applications.
  • Natural or Riven:Retains the stone's natural texture, contributing to slip resistance and a traditional appearance.
