ICAR Concrete Rheometer
The ICAR concrete rheometer is a new, multifunctional, and lightweight concrete rheometer used to measure concrete from low slump to self consolidating. The ICAR concrete rheometer has a simple design and can be used in various aspects of concrete construction, from research and development to on-site quality control.
Characteristics of ICAR Concrete Rheometer

• Improve the quality and performance of concrete
• Improve worker productivity
Accelerate the promotion and use of brand new, inexpensive, and materials
technical specifications
• Measure from low slump to self consolidating concrete
• Controllable speed, four piece impeller, height 125 mm, diameter 125 mm
• Measurable aggregate size 6 to 32mm
• Slump: Self consolidating concrete 50 to 75 mm
• Impeller rotation speed: 0.001 rps to 0.6 rps
ICAR software can measure concrete thixotropy through stress growth or flow curves. The ICAR rheometer automatically calculates the basic unit Bingham rheological parameters - yield stress and plastic viscosity. Software driven rheometer, record data, calculate test results, and store data.
Typically, the experimental process only takes 30 to 40 seconds
Lightweight, low-cost rheometer for concrete
Question:
The slump test is not applicable to many increasingly new types of concrete. The new materials and mix proportions have increased the difficulty of determining the workability of concrete, which can lead to incorrect slump test results. Although the application of liquid rheology in concrete has been proven to be promising, traditional rheometers are bulky and expensive, making them unsuitable for on-site use.
new method:
The rheometer developed by International Aggregate Research (ICAR) at the University of Texas is precisely designed to meet industry needs and break through the limitations of today's workability measurement methods. The ICAR rheometer is similar in size to a hand drill, including a lightweight four piece impeller. When in use, insert the impeller into the fresh concrete and rotate it at different speeds. The torque corresponding to different speeds acting on the impeller is recorded and used to calculate the Bingham rheological parameters in basic units: yield stress and plastic viscosity. All experimental operations are automated and can be completed within 60 seconds. In addition, the ICAR rheometer can be used for stress growth experiments, monitoring and maintaining the state of workability, and measuring thixotropy.
Application of ICAR Concrete Rheometer
The Danish ICAR concrete rheometer provides a scientific and relevant method for measurement and workability. It can be used in various stages of concrete production and construction. The users include construction personnel, manufacturers, material suppliers, experimental institutions, and researchers. Its application can be found in concrete mixing, quality control, and research. It is very suitable for bringing to construction sites, and can even be packed into hand luggage and carried on airplanes. The ICAR rheometer can be used to measure slump exceeding 50 mm (2 inches) and is particularly suitable for self consolidating concrete.
