Shrinkage

Mortras and concretes are changing its voulume during setting and hardening. Many facors 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 dosn't matter. (maybe you get, due to the shrinkage,  some percent less cubicmeters  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.

Schleibinger offers sveral instruments to measure this volume change from the early beginning  with high precision.
