Guidelines for Natural Stone Products in Connection with European Standards

Area of Science:

• Geology and Materials Science
• Engineering and Construction Materials

Background:

• Selecting ornamental stones requires technical data on durability, service life, and aesthetics.
• Existing methods often lack quantitative data for stone usability and performance.

Purpose of the Study:

• To develop a quantitative classification system for natural stone products.
• To establish minimum limit values for critical rock properties based on European standards.

Main Methods:

• Listing fundamental physical and mechanical rock properties according to European standards.
• Conducting retrospective analyses of ornamental stone applications.
• Proposing minimum limit values for different stone applications.

Main Results:

• A quantitative classification system for natural stone products is proposed.
• Minimum limit values for key physical and mechanical properties are suggested.
• The study provides guidance for selecting suitable natural stones.

Conclusions:

• The proposed classification system aids engineers in selecting appropriate natural stones.
• This contributes to the dimension stone industry by defining usability criteria.
• The study facilitates informed decisions for ornamental stone applications.
