A rheometer is a laboratory device used to measure the way in which a liquid, suspension or slurry flows in response to applied forces. It is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer. It measures the rheology of the fluid.
Transferring all the fresh property qualities of self-consolidating concrete (SCC) from the lab to the field is now much easier. The ICAR rheometer is a fully portable test device. The unit is about the size of a drill and can be operated by hand or positioned above a standard container. It is accurate in measuring a flow curve or performing a stress growth test for almost the full range of concrete workability, ranging from a 2-inch slump to SCC.
