Barcy Limestone

Barcy Limestone, also known as Vilhonneur Bercy Limestone, is a prestigious type of beige limestone quarried in Vilhonneur, Charente, France. Known for its elegance and durability, it is highly regarded in the construction and renovation industry. Below is a detailed description covering its physical and mechanical properties, chemical and mineral compositions, as well as its usage, maintenance, and surface finish options.

Physical and Mechanical Properties

• Color: Primarily Beige with subtle variations and fine grain
• Water Absorption: 0.34%
• Density: 2200 - 2400 kg/m³ (according to NF EN 1936)
• Flexural Strength: 5 - 7 MPa (according to NF EN 12372)
• Compressive Strength: 35 - 45 MPa (according to NF B 10-509)
• Hardness: Typically falls on the lower end of the hardness scale due to limestone's natural composition (specific Mohs hardness not provided)
• Porosity: Moderately low porosity which contributes to its durability
• Slip Resistance: Generally provides moderate slip resistance, but specific ratings may vary depending on finish

Chemical and Mineral Compositions

While exact compositions can differ slightly based on specific geological conditions:

• Calcium Carbonate (CaCO3): Predominantly around 96-98%
• Magnesium Carbonate (MgCO3): Typically around 0.5-2%
• Silica (SiO2) and other minerals: Small amounts can be present, adding to structural integrity

Usage

• Applications: Suitable for both interior and exterior applications
• Flooring: Popular in residential and commercial properties for its classic appearance
• Wall Cladding: Often used for its aesthetic appeal
• Countertops: Provides a sophisticated look, often in kitchens and bathrooms
• Fireplaces and Facades: Used in architectural features for a timeless elegance
• Construction Projects: Ideal for restoration of historical buildings due to its traditional provenance and look

Maintenance

• Sealing: Regular sealing is recommended to maintain its appearance and resistance to staining
• Cleaning: Use a pH-neutral cleaner or mild soap; avoid acidic or abrasive cleaners that can damage the surface
• Regular Dusting/ Wiping: Helps in maintaining its luster and prevents dirt accumulation

Cutting Sizes and Surface Finish Options

• Typical Cutting Sizes: Available in various standard and custom sizes, typically ranging from small tiles (e.g., 30x30 cm) to large slabs (e.g., 120x60 cm)
• Common Surface Finish Options:
• Honed: Smooth matte finish that enhances the natural color
• Polished: Glossy finish that adds to its vibrant elegance
• Antique: Creates a weathered appearance, contributing to traditional aesthetics
• Brushed/ Bush-Hammered: Offers a textured surface which can enhance slip resistance

Barcy Limestone is often chosen for its balance of beauty, practicality, and cost-effectiveness relative to other luxury stones like marble. Its combination of durability and aesthetic versatility makes it a popular choice for many high-end design applications.

• Apparent bulk density: 2200 to 2400 kg/m³ (NF EN 1936)
