Product description
NELD-CRH610 01 is a concrete rheometer which can measure the plastic viscosity, yield stress and maximum yield stress of freshly mixed concrete. The instrument has a simple structure, is easy to operate, and the measurement time is less than 1 min. It is suitable for all aspects of engineering production and construction, including construction units, equipment manufacturers, and mixing station laboratories, etc.
NELD-CRH610 Rheometer is a new portable multi-functional concrete rheometer, which is designed and developed by NELD according to the experience of concrete laboratory and field measurement. The instrument is suitable for static and dynamic rheological performance testing of fresh concrete. It is used to test the rheological properties of concrete with aggregate size up to 32mm, and can be used for concrete proportion design and on-site rheological monitoring of fresh concrete. It is suitable for the rheological characterization of concrete with different aggregate size ranges, including the static yield stress, dynamic yield stress and plastic viscosity of freshly mixed concrete. The instrument can also analyze the thixotropy of fresh concrete.
