Flakiness & Elongation Gauges

Determination of Flakiness & Elongation

Aggregates which are flaky and/or elongated will often lower the workability of a concrete mix and may also affect long term durability.

In bituminious mixtures, flaky aggregates make for a harsh mix and may also crack and break up during compacting by rolling. The flakiness of aggregates is determined by measuring the thickness of individual particles.

Techno Test offers thickness gauge and length gauge with ISI certification mark as per IS: 2386 to check flakiness index and elongation index of the aggregate respectively.
