General Information


Concrete TSTM / ADTM setup


The Temperature-Stress Testing Machine (TSTM) is a horizontal steel frame in which hardening concrete specimens can be loaded in compression and in tension under various hardening conditions. Both load-controlled and deformation-controlled experiments can be performed. The Autogenous Deformation Testing Machine (ADTM) consists of a prismatic mould made with thin steel plates provided with an external insulating material.

Key words:

autogenous deformation, temperature stress, testing machine, ADTM, TSTM

Main application:

The TSTM allowes measuring stress development due to restrained deformations but also creep and relaxation behavior in compression and in tension under prescribed thermal conditions. The ADTM performs measurements of the autogenous deformations.
