Swell Test Apparatus
Product Code : JA-ST-9838
The Swell Test Apparatus (SKU JA-ST-9838) determines the swelling pressure that a soil specimen develops when it is soaked in water after being moulded to a chosen density at a known moisture content. The load needed to stop the specimen swelling passes through a perforated swell plate and a load transfer bar to a proving ring on the lead screw of a hand-operated load frame. A soaking tank and a grooved mould base let water reach the specimen.

Frequently asked questions
How is the swelling pressure measured?
The load applied to restrain swelling is carried through a perforated swell plate and a load transfer bar to a proving ring attached to the lead screw of a hand-operated load frame.
How is the specimen saturated?
It is soaked in the soaking tank, and the channels, radial grooves and connecting holes in the mould base let water reach the specimen.
How are specimens prepared?
Specimens are moulded to the desired density at a known moisture content before soaking.
