Description
Technical Field

[0002] Cement paste viscosity refers to the flow properties of the slurry formed by mixing cement and water, that is, the resistance of cement paste under external force. Viscosity is an important indicator of liquid fluidity. It reflects the strength of the interaction between molecules inside the liquid. Testing the viscosity of cement paste can play an important role in controlling the fluidity of concrete, ensuring the sealing effect of cement paste, and evaluating the quality of cement.

At the same time, there is a lack of constant temperature measures when the sample is prepared. During the preparation and stirring process of the sample, a hydration heat reaction occurs, resulting in the sample temperature being too high, affecting the accuracy of the test results.
