Viscometer 5 - contec.is
The ConTec-Viscometer 5 is a coaxial cylinder viscometer for course particle suspension that is suitable to measure the rheological properties of cement paste, mortar and concrete with about 120mm slump or higher. The rheological properties are described by the fundamental parameters in the Bingham model, the yield value, and the plastic viscosity.

2023年10月14日 · The ConTec Viscometer 5 is a coaxial cylinders rheometer for coarse particle suspensions such as cement paste, grout, mortars, cement-based repair materials, and concrete. It is based on the concentric cylinders principle already described in Sect. 3.2.2 , where the inner cylinder measures torque T and the outer cylinder rotates at variable ...
Empirical Test Methods to Evaluate Rheological Properties of …
2023年10月14日 · The plastic viscosity was determined with the ICAR rheometer and was transformed into values calculated for a Contec 5 co-axial rheometer. The figure also shows the data for highly workable concrete (HWC) with a slump flow of 300 to 550 mm.
controlled coaxial cylinder rheometers: DV3T HB, Brookfield (DV3T) and ConTec Viscometer 5 (CTV5). The main differences between these rheometers are the specimen volume, the gap size and the geometry of the inner cylinder (Figure 3). The geometry of the CTV 5 …
Schematic diagram of the Contec 5 rheometer (unit: mm).
Contec 5 coaxial cylinder rheometer was used to determine the rheology of UHPC mortars, as shown in Fig. 3. Each mixture was replicated three times to assess the repeatability of results, and...
Particle migration during concrete rheometry: How bad is it?
2016年12月27日 · In this paper, the importance of particle migration on concrete rheometry is discussed based on simultaneous measurements carried out using the ConTec Viscometer 5 with the regular bucket and with a larger bucket, as well as measurements using the ICAR rheometer.
In this paper, two rheometers – Contec Viscometer 5 and Tattersall Mk-II rheometer – are compared for non-linear behaviour. After transformation of the data into fundamental rheological units, the results indicate that the Tattersall Mk-II rheometer shows very similar
This paper discusses the comparison of two coaxial cylinders rheometers: the ConTec Viscometer 5 and the ICAR-rheometer. The results of different SCC are compared, employing for both...
