A rheometer for mortar is a multifunctional rotating mechanical instrument used to measure rheological properties and ease of flow, capable of measuring the plastic viscosity, yield stress, and maximum yield stress of fresh mixed mortar. The instrument is simple in structure, easy to operate, and takes no more than 1 minute to measure. It is suitable for all stages of scientific research, education, and engineering construction, and is applicable to universities, research institutes, construction companies, material manufacturers, and mixing station laboratories.

The NELD-CRV610 rheometer is capable of testing the rheological properties of cementitious mixtures containing fine aggregates with a maximum particle size of 8mm, such as mortar, 3D printed concrete, self-compacting concrete, fine aggregate concrete, and slurry. This rheometer can directly provide data such as rheological curves and parameters, the relationship between rheological properties and construction performance, the relationship between solidification behavior and time at a certain mixing speed, and the influence of concrete additives and inorganic admixtures on construction performance. By further utilizing these data, the proportioning of mortar (concrete) can be optimized. The instrument can also analyze the rheological properties of 3D printing materials.
