Specimen shapesand dimensions Concrete has a heterogeneousstructure, which requires large specimens. These are either cubes with an equal length of edges of 100, 150, 200 or 300 mm or > Modern building materials consistof many different raw materials as for example natural and artificial minerals, plastics, wood or metals and they are offered in various types of products: as powder, masses, bulk goods, foils, plates, stones and form elements or prefabricated components, as for example wall elements, supports, stairs, etc. They are used for the preparation of foundations, walls and ceilings,...

Specimen after the test with nonuniform (top) and uniform (bottom) stress distribution In this way the test data dispersionscan be reduced to values below 1% and the actual strength of the concrete can finally be determined. The type of load application used is revealed on the specimens break graphs.A so-called strain cylinder test iscarried out to test and to prove the efficiency of these measures. This test has been developed particularly for compression testing machines for concrete (max. test load > 1200 kN ). It is part of the European test standards resp. of the national supplementary...

Device to determine the stability of cement which may change when expanding during hydration. For this purpose up to 16 specimen bars can be stored in a bath of boiling water or water vapor. The heating cycle e.g. heating up to 100ֺC within 30 min and keeping this temperature constant for more than 3 h is regulated automatically and with a high accuracy (accurate to 0.1ֺC). Setting time and setting temperature may vary according to the requirements in question.Easy and safe handling. > Device to determine theconcentration of free lime in cement or cement clinker. For this purpose the...

With this control system, the oilsupply to the cylinder is controlled. The servovalve is always under pressure. The higher losses of power for some applications requires an oil cooling. Each load frame connected to a common Powerbox needs its own servo valve adapted to the corresponding power requirementand directly located at the cylinder. The advantages of this type of control are, for example, minimum reaction times and high control accuracies, which are particularly needed for research and develop- ment tasks. All the corresponding units are integrated in one working table. This table...
