PROPERTIES<br />
For rapid collection of samples from<br />
aggregates, sand and fillers, a sample<br />
divider is required.<br />
Supplied complete with three containers.<br />

Riffle Sample Divider<br />
System Description<br />
Consists of a metal box, fitted with a<br />
series of chutes of equal width, which<br />
discharge the material alternatively in<br />
opposite directions into separate pans.<br />
The chutes of the riffle are steep enough<br />
to allow rapid flowing of the material.<br />
Determination of Flakiness &<br />
Elongation<br />
System Description<br />
Aggregates that are flaky and/or<br />
elongated will often lower the work ability<br />
of a concrete mix, and may also<br />
affect long term durability. In bituminious<br />
mixtures, flaky aggregates make <strong>for</strong> a<br />
harsh mix and may also crack and break<br />
up during compacting by rolling. The<br />
flakiness of aggregate is determined by<br />
measuring the thickness of individual<br />
particles. We offer both a thickness<br />
gauge and length gauge to check<br />
flakiness index and elongation index of<br />
the aggregate respectively.<br />
