One frame.
The whole strength picture.
Sand fails in more than one direction. The VUD III measures compression, shear, splitting, tensile, transverse, twin transverse and deformation on a single bench frame, and sends each reading to the cloud.
A mould does not fail the way the test bench squeezes it.
Green compression is the number most labs quote, and it earns its place. But a core snaps in tension when it is lifted, a corner lets go in shear, a shell bar bends and breaks in transverse loading, and a mould that will not deform at all tends to crack instead.
Testing one mode describes one failure. The VUD III covers the set on the same frame and the same specimen standard, so the numbers stay comparable and the lab keeps one calibrated instrument rather than several.
Seven ways sand gives way.
Compression is built in. The other modes come from attachments that mount on the same frame, so the machine grows with the lab.
Repeatable hands, not steady hands.
Load the specimen, press start.
A motorised loading mechanism applies the load at a controlled rate, so the reading does not depend on how fast an operator turns a wheel.
Calibrated against known kits.
VKSL for low strength and VKSH for high strength, with NABL-traceable calibration and a certificate for the quality file.
Add a mode when the work calls for it.
Shear, splitting, tensile, transverse, twin transverse, deformation and high-dry attachments all fit the same frame.
Readings, in the cloud with V-Sync
The VUD III connects to the plant network and syncs to the cloud, so a shift can be trended from a browser and a service engineer can review the same data remotely. See how V-Sync works →
The numbers a lab plans around.
Standard supply covers green compression on an AFS or metric specimen, with the compression pad set, a calibration certificate and the manual. Attachments extend the modes.
