A dilatometer is a precision instrument for the measurement of dimensional changes in material as a function of temperature. Dilatometry can be used to test a wide range of material including traditional and advanced ceramics, glasses, metals, and polymers.

Why dilatometer test is done?

The Flat Dilatometer Test (DMT) is an in-situ testing method used to determine the strength and deformation characteristics of fine-grained soils. The corrected DMT results are used to obtain information on soil stratigraphy, in situ state of stress, shear strength and deformation properties. ...

Why horizontal dilatometer is preferable than vertical dilatometer?

Both versions provide accurate results due to their unique differential measurement configuration. The horizontal structure of these dilatometers ensures optimal temperature uniformity and precludes air currents matching with convection.
