Viskomat NT - Rheometer f. Mortar and Paste

ApplicationViskomat NT

The viskomat NT is a versatile rotational viscometer for determine the workabilty of fine-grained building materials such as cement paste, mortar, fine concrete, plaster etc. with a maximum particle size of 2 mm. You can obtain information on:

  1. flow curves and rheological parameters

  2. temperature dependent workability properties

  3. stiffening behaviour as a function of time an stirring speed

  4. effects of concrete admixtures and mineral blending agents on workability



Not only is all this information useful for the materials themselves, but tests have shown that trends established, for example, in mortar are reflected in the behaviour of concrete at full scale.

Construction and operating principles

The viskomat NT is a true speed controlled viscometer driven by a high precision synchron motor. Each rotation is resolved whithin 200.000 steps. It allows ramping from 0.001 rpm to 400 rpm in both directions to record flow curves and yield points. The torque up to ±250 Nmm or ±500 Nmm is measured by a special transducer. Sphere Probe

The standard measuring system consists of a stationary paddle which is mounted concentrically in a rotating cylindrical sample container. As the sample flows around the paddle the shear resistance generates a torque which is continuously monitored electronically. The paddle is mounted on a measuring head, which runs up and down automatically to allow easy filling, emptying and cleaning of the sample container. The sample container is mounted on a speed drive shaft.

The temperature is measured by a sensor located within the measuring paddles. 

All the electronic is housed in a separate case. One powerful microprocessor and two special signal processors does their work there. An online display shows torque, time and temperature during the measurement in a graphical way. The electronic has  an network interface. With the network interface you can integrate the Viskomat NT in any computer network. The Viskomat NT has an built in WEB Server so any WEB browser like Internet Explorer (R) , Firefox, Opera or others, may be used as user interface, the Viskomat NT can be remote controlled from any workplace in your local area network.  No extra software has to be installed on your PC. 

 

Features

  • robust apparatus for industrial environments, quality control, research and development

  • informative, easy to use test procedures

  • automatic running of predefined test procedures which can be either standardized or tailored to your own requirementsVane Probe

  • inhomogeneous materials measurable with particles up to 2 mm using special paddles to avoid separation and segregation.

User

The Viskomat  is widely used in many companies, Universities or reasearch centers:
