SLAKE DURABILITY APPARATUS AZA1005
AZA1005 Slake Durability Apparatus is a high-precision laboratory testing machine designed to determine the Slake Durability Index (SDI) of weak and weather-sensitive rocks. It simulates natural wetting and drying cycles to evaluate how rock specimens deteriorate over time when exposed to environmental conditions.
This apparatus is widely used in geotechnical engineering, mining, civil construction, and academic research to assess the long-term stability of rocks such as shale, mudstone, marl, and claystone.
Description
Key Features
• Evaluates slake durability index of weak rocks
• Twin stainless steel mesh drums for higher accuracy
• Conforms to ASTM D4644 and ISRM Suggested Methods
• Stainless steel water tank and corrosion-resistant structure
• Constant-speed geared motor with uniform rotation
• Digital timer for precise cycle control
• Suitable for geotechnical laboratories and universities
Working Principle
The test reproduces environmental weathering by rotating rock samples inside mesh drums immersed in water.
Test Cycle Process:
-
Samples are oven dried and weighed (W₁)
-
Placed in rotating mesh drums and immersed in water
-
Drums rotate continuously for 10 minutes
-
Samples are dried again and reweighed (W₂)
-
The cycle is repeated twice
Slake Durability Index (SDI) Formula:
SDI = (W₂ / W₁) × 100
A higher SDI value indicates stronger resistance to weathering.
Applications
• Slope stability studies
• Tunnel and underground projects
• Dam and embankment safety analysis
• Highway and rock cut investigations
• Academic and research laboratories
