(Scale) Testing

Soil test
Clients: Dutch and international contractors, IHC Holland, Dutch Government More than 6000 samples have been collected and analysed in the MTI soil laboratory, especially to determine the dredgeability of the material and the characteristics important for hydraulic transport. Samples range from silts, clays, sand, gravel, coral to soft rock such as salt, chalk and sandstone. Important soil characteristics that have been determined in the laboratory are grain size distribution, particle shape, viscosity, Atterberg limits, organic content, mineral content, specific gravity, porosity, unconfined compression strength, shear strength etc.

Pilot tests

1999
Title: Recycling of plastic contents from autorecycling Client: Autorecycling Netherlands, Delft Technical University Tests were carried out with a jig installation for plastic material recycled from car waste.

1998
Title: Glass recycling Client: Glass Recycling BRD Evaluation and testing of jigs for the recycling of glass. A number of samples were tested in a pilot plant.

1996/1997
Title: Trail testing of a synchrocrusher concept at a quarry In association with: Van der Zanden and Novem Based on the results of the testing project performed at MTI, a second commercial crusher was rebuilt and tested on site at a quarry in Belgium. Although as stand alone these tests showed the earlier developed concepts.

Scale Tests in MTI Laboratory
Scale tests of the counter current sand classifier, including grain size analysis and performance control. IHC Holland, 1994-1995. Testing of the IHC environmental cutter, to be used for dredging on Lake Balaton, Hungary. IHC Holland, 1991. Testing hydrofenders for sluices with several types of material by using a hydrostatic bearing. Ministry of Public Works and Waterways, 1989-1993.

1990
Title: Transport, degradation and sedimentation tests on blue chalk Client: Transmanche, France. As part of a study to find the best method to dispose material excavated from the Channel tunnel between France and England, scale tests were carried out on a 300 mm diameter test circuit in MTI Laboratory for testing the hydraulic transport option of excavated materials from inside the tunnel to a disposal site on surface. Both pipeline resistance, material degradation and sedimentation tests were performed to determine the layout of the pumping system and the required power.
