ISI Marked - Length Gauge

Purpose:

This instrument is used to determine the elongation index of aggregates. Particle is elongated when its length (longest dimension) is more than 1.8 of the midsize of the sieve fraction.

Significance and Use:

This method classifies aggregate elongation by measuring the length of individual particles. The test is not applicable to material retained on a 63.0 mm BS test sieve.

Construction Details:

1. ISI Marked
2. Consists of a hard wood base with vertically mounted S.S. studs 
3. Eight S.S. studs are mounted.
4. Aggregate to be classified is separated into seven sieve fractions from 63 to 6.3mm, and each fraction is examined separately.
5. The mass of all elongated particles as percent of the sample is the elongation index.
6. The distance between nails is applied according to following table.
