Abstract
A positive stirring consistometer cup includes a pair of wall blade members having radially inwardly extending blades which cooperate with radially outwardly extending blades of a paddle to uniformly apply shear throughout a substance to be tested. A split sleeve assembly eliminates an outer dead space, and an enlarged spacer member mounted on the shaft of the paddle eliminates an inner dead space, thereby enhancing the uniformity of the shear throughout the substance. A centralizing assembly centers the stationary paddle while causing a minimum of friction and wear to occur on the shaft of the paddle. In a method of using the positive stirring consistometer cup, the blades of the wall blade members and of the paddle stop in substantially aligned, coplanar relationship to facilitate cleaning of the elements after a test is concluded.
