1. Physical Absorption Properties The "density" of a stone determines its lifespan and how much sealer it will require. Water Absorption (ASTM C97): Determines how much moisture the stone "drinks." Granite: Usually 0.4% (Highly resistant). Sandstone/Limestone: Can be 5% (Prone to weathering and staining). Bulk Specific Gravity: Measures the density. Heavier stones are generally more durable but require stronger structural anchors for wall cladding. Porosity: Identifying the microscopic voids that can trap water, which leads to "freeze-thaw" cracking in cold climates. 2. Mechanical Strength Testing These tests are critical for stones used as structural elements, stairs, or heavy flooring. Compressive Strength (ASTM C170): Measures the crushing load the stone can handle. This is the "Identity Test" for granite used in commercial flooring. Flexural Strength (ASTM C880): Measures the "bending" strength. This is the most important test for Thin Stone Cladding on buildings, ensuring the stone won't snap under high wind loads.

Key Features: Determines physical properties such as hardness, density, water absorption, and compressive strength. Ensures quality, durability, and compliance with industry standards for construction and decorative use. Provides reliable test reports for performance validation and material selection.
