Change in the volume of a soil specimen is related to its pore-fluid.
In saturated soils, volume change can be measured by monitoring the inflow or outflow of pore water from the specimen.
Measure of Volume Change
In order to measure volume changes during test, two solutions are proposed:
- Double burette apparatus
- Standard or automatic volume gauge with displacement transducer or dial gauge.
S358 Double Burette Volume Change Apparatus
It is composed by two measuring burettes which are placed inside a perspex tube and connected directly to a reverse valve system.
A by-pass valve is also included.
Capacity: 200ml
Accuracy: 0.2ml
Dimensions: 230x270x860 mm
Weight: 5 kg approx.
S338N Volume Gauge
The unit consists of a metallic air/water interface.
It measures the water volume changes inside the sample.
It has to be used with linear strain transducer, or dial gauge.
Capacity: 100 ml
Accuracy: better than 0.1 ml.
Dimensions: 180x180x240 mm
Weight: 4.7 kg approx.
Easy de-airing of bottom and top chambers.
Supplied complete measuring device and mounting block.
