Manufacturer: Toni Technik

Technical data / description:

- Models (2 pieces): ToniCAL 7338 (1-cell), ToniCAL Trio 7339 (3-cell).

- Control and recording of measured values with Toni Technik's own software (ToniCAL Software).

Applications: Determination of the reaction kinetics of cementitious materials.

- Water and the cementitious material to be tested are mixed in a test tube, which is located in a thermally insulated, closed test chamber. This chamber also contains a sample that has already been completely hydrogenated (= reference sample).

- The ambient temperature of the two samples is the same (= isothermal).

- The water is added by means of a syringe or a post-injection module. The latter enables the separate addition of further substances, e.g. an accelerator.

- During the experiment, the thermoelectric voltage is continuously recorded as a measure of the amount of heat released.

Technical data / description:

- Test frequencies between 50 kHz and 20 MHz

- Two probes each for longitudinal and transverse waves (Panametrics/ Olympus)

- Pulse generator: Panametrics 5077 PR

    o Variable pulse voltage and repetition rate

    o Variable amplification or filtering

- Digital oscilloscope LeCroy Waverunner 62xi for signal playback and storage

- Probe holders and adapters

- Delay lines and reference specimens

Applications:

- Measurements of signal transit times or sound velocities in a variety of materials (metals, rocks, wood, plastics, bones, concrete, cement ...)

- Determination of material parameters (modulus of elasticity, components of the stiffness tensor, Poisson’s ratio)

- Test of isotropic and anisotropic materials

- Determination of the influence of temperature, humidity and sample age on material parameters
