ICAR Plus Rheometer

A simple to operate instrument that can be used for:

• Research and development to characterize the influence of new materials on concrete rheology
• Optimizing mixture proportions so that the resulting concrete flows readily but is resistant to segregation (especially important for self-consolidating concrete)
• On-site quality control

The Rheometer is designed to characterize the static yield stress, the dynamic yield stress and plastic viscosity of the concrete. By determining the dynamic flow curves of concretes with different mixture proportions and type of admixtures, an optimum balance between ease of flow and resistance to segregation can be realized. These types of determinations cannot be done using conventional slump-based tests.

The ICAR Plus Rheometer is the successor to the ICAR Rheometer. This device is provided with a stronger motor (Integrated Servo Motor), digital based electronics and more comprehensive software. The main advantage of the ICAR Plus is its digital verification process, allowing users to always have a ready to use system under any environment and working condition. ICAR Plus will always be calibrated by the user on-site and can be verified in the laboratory with the same silicone as its predecessor ICAR Rheometer.

Digital Calibration can be performed by user anytime  The rheometer performs static stress growth test and dynamic flow curve tests.  Software controls tests and computes static yield stress, dynamic yield stress, and plastic viscosity in fundamental units The yield stress and flow tests take only 1 minute.

Note that the concrete must have a slump greater than 75 mm, otherwise it is too stiff for testing by the apparatus. Also, the nominal maximum size of aggregate is 32 mm for largest available container. This kit includes a container for 19mm NMSA aggregate.

Kit includes: 

• Motor drive/torque meter unit 
• Power cord for motor drive/torque meter unit
• Base plate for attaching motor drive/torque meter unit to container
• Container for 19 mm NMSA aggregate – standard
• Four-blade vane for 19 mm NMSA aggregate. Vane is 127 mm in height and diameter
• Laptop computer with installed software and carrying case, USB cable, Software on CD-ROM and user manual
• Carrying case for Rheometer and accessories   Note: The Container ships with the set but not inside the case.

Silicone oil for verification of instrument is available separately.
