Aggregates which are flaky and/or elongated will often lower the workability of a concrete mix and may also affect long term durability. In bituminous mixtures, flaky aggregates make for a harsh mix and may also crack and break up during compacting by rolling. The flakiness of aggregate is determined by measuring the thickness of individual particles. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively.
Used to determine the flakiness index of the aggregate. The aggregate particles are to be considered flaky, if their thickness is less than 0.6 of their nominal size. It consists of a frame with sliding panel with accurate slots of different standard width and length, the complete assembly is chrome plated or powder coated.
