Materials Testing
The Schleibinger range of testing systems is specifically designed and developed for the testing of construction materials such as cement paste, mortar, fine concrete, plaster etc. The range includes rotational viscometers, compact viscometers, freeze/thaw units, shrinkage cones and shrinkage/expansion units.

Durability
Durability is, beneath the strength, one of the most important properties of concrete. Beneath the freeze-thaw resistance also the ASR resistance comes more and more in the public focus.
Rheometers
Rheometers for fresh concrete, mortar and paste.
BT2 – SCC Rheometer for Fresh Concrete
Setting & Maturity
Setting and hardening of mortar and concrete may measured by several methods. A popular test is the so called needle or Vicat test. Schleibinger is offering two test methods: Estimating and simulating the strength development by temperature measurement and Measuring the e.modulus of mortar by determining the ultrasonic speed inside the material.
Ultrasonic Setting Measurement
Shrinkage
Mortars and concretes are changing its volume during setting and hardening. Many factors are influencing this mechanism: temperature changes, drying, van-der Waals forces between the small high surface particles, growing and shape changing of crystals, volume change of the aggregates, and some other known and also already unknown reasons. If the concrete is still in the fluid state, volume change doesn’t matter. (maybe you get, due to the shrinkage, some percent less cubic meters of concrete volume then ordered). If hardening begins, shrinkage and expansion will cause inner strains. If this strain is higher then the strength inner cracks or other may appear.
