Cement Mortar Liquidity Testing Method by Rheological Properties
A cement mortar mixer that can test torque is designed to realize online observation of working performance of the cement mortar and to predict cement mortar slump. The influence of different rotating speeds and mixing times on cement mortar quality is analyzed using factors of slump and torque. The best stirring speed is determined to be and the best mixing time 60–180 s. The relation between cement mortar slump and torque at different shear rates is studied, and different power functions for different shear rates are found. At a given shear rate, i.e., a rotation speed of , the relation between slump and torque is set up, which could provide a test method and theoretical basis for cement mortar online quality control and slump forecast.
