Density Basket

Density Basket – Specific Gravity & Water Absorption Testing

The Density Basket is a key accessory used in determining the specific gravity and water absorption of coarse aggregates. Constructed with durable stainless steel mesh and conforming to ASTM C127, AASHTO T85, and BS 812 standards, it ensures consistent, repeatable results in concrete mix design and aggregate quality control. Designed for suspension in water using a balance frame setup, the basket is compatible with most laboratory buoyancy balances and testing frameworks.

Key Features of Density Basket

• Reinforced Mesh Construction: Made from robust No. 8 stainless steel wire mesh for long-lasting performance.

• Precision Dimensions: Standard size of 8” diameter x 8” height (203 × 203 mm) for compatibility with common test setups.

• Suspension Handle: Fitted with a bail-type handle for secure and balanced hanging during submerged testing.

• Corrosion-Resistant Design: Ideal for repeated immersion and lab use with minimal maintenance.

• Standard-Compliant: Conforms to ASTM C127, AASHTO T85, and equivalent EN/BS standards for reliable results.

Applications

• Specific Gravity Testing: Calculates the relative density of coarse aggregates using the water displacement method.

• Water Absorption Measurement: Determines the moisture retention capability of aggregates, essential for accurate concrete mix design.

• Aggregate Quality Control: Used in labs and quarries to assess the durability and porosity of aggregates.

• Educational and Research Use: Demonstrates fundamental material property testing in academic and R&D settings.
