Flakiness and Elongation Gauge Set for Coarse Aggregate

Sets of thickness and length gauges with sieve plates to measure particle shape of coarse aggregate for roads and concrete. Used at crushers, hot-mix plants and QC labs.

Specification

Aggregate particles are tested through slotted thickness gauge plates and length gauges to determine flakiness and elongation indices. These shape indices affect workability, packing and bitumen demand. The set covers the usual size fractions from 63 mm to 6.3 mm.

Features

• Precision-machined brass or steel gauge plates
• Covers 63 mm to 6.3 mm fractions
• Complete with metal length gauge
• Fixed slot widths verified against standards
• Wooden carry box
