This fully automatic apparatus is designed to perform water permeability tests on cubic concrete specimens max 150 mm side and cylinder
specimens max 160 mm diameter. The specimens are submitted to hydrostatic stress for a pre-set period. The water permeated through the
test specimen is directly collected and measured into a graduated cylinder.
It is therefore possible to determine the permeability coefficient in cm/sec. (Darcy coefficient) by the following formula:
The equipment consists of a strong metallic frame holding four cells
which are hot-galvanized for anti-corrosion protection.
Each cell includes a pressure control manometer.
A re-chargeable compensation plenum chamber is included as part
of the test.
The pressure is adjustable from 0 to 30 bar and it is supplied by
an automatic pump of variable supply, to achieve the most suitable
installation for the specimen under test.
Water feed is direct from water inlet.
Seal pressure obtained through special and practical seal devices
which maintain and simplify the use of the machine.
It is possible to use one or more cells together, and specimens also
of different size (cubes/cylinders).
The specimen’s sealing system is achieved through a practical and
speedy, user-friendly device.
Supplied complete with four cells, four graduated cylinders, epoxy
resin and accessories. The sealing devices are not included in
the standard package and must be ordered separately.
