Sand Absorption Cone and Tamper

Sand Absorption Cone and Tamper – Specific Gravity & Water Absorption of Fine Aggregates

The Sand Absorption Cone and Tamper is a precision-engineered tool used in laboratory testing to determine the specific gravity, apparent density, and water absorption of fine aggregates (particles smaller than 10 mm). This apparatus is widely used in civil engineering and materials testing to evaluate the physical characteristics of sand and fine aggregates, which are critical in the design of concrete mixes and pavement materials.

The equipment consists of a brass cone mold and a tamping rod, both built to strict dimensional tolerances and in compliance with ASTM C128 and BS 812-2 standards. The cone is made of plated steel to prevent corrosion and ensure long-term durability in tough lab environments.

Key Features of the Sand Absorption Cone and Tamper

Corrosion-Resistant Build: Constructed from plated steel for long-lasting performance.

Standardized Design: Cone dimensions follow international standards — 40 mm (top), 90 mm (base), and 75 mm (height).

Precision Tamping Rod: Includes a 25 mm diameter base and 180 mm height, approx. 340g in weight for accurate compaction.

Complies with ASTM and BS Standards: Ensures consistent and repeatable results in quality control labs.

Compact & Easy to Use: Lightweight and ergonomic for ease of handling during testing procedures.

Applications of the Sand Absorption Cone and Tamper

Civil Engineering Labs: Determine particle density and water absorption for aggregate quality control.

Construction Materials Testing: Evaluate fine aggregate behavior for use in concrete, mortar, and asphalt mixes.

Educational Use: Demonstrations in construction materials and soil mechanics labs.

Research & Development: Analyze fine aggregate properties for new mix formulations.
