Abstract
The author has measured the rheological properties of time-independent suspensions (MgCO3-water slurry and Ca(OH)2-water slurry)by means of a rotational viscometer and pipe flowing.
First he observed that the viscosity of suspension depends largely on the aggregative state of suspended solid in the liquid by the rotational viscometer (Fig. 1).
From the results of the experiment of pipe flow where the range of rate of shear is very wide (Fig. 4), he found that the rheological behavior of suspension is not always constant, but, according to the magnitude of shear rate, that is the degree of aggregation of suspended solid, varies its form from Bingham plastic (Fig. 6) to psuedo-plastic (Fig. 2, Fig. 3) and further to Newtonian fluid (Fig. 5).
