Title: Influence of Acrylic Polymers on the Rheology of Mortars
Author(s): S. Maximilein, J. Ambroise, and J. Pera

Abstract:Influence of an acrylic polymer on the rheology of mortars was investigated using a mixer in which the torque on the impeller shaft was continuously measured. The polymer was added to specific mortars either alone or in combination with aqueous solutions of sulfonated naphthalene formaldehyde condensate or sulfonated melamine formaldehyde condensate. Two cements were ground from two different clinkers to specific surfaces of 270 and 400 m 2/kg, respectively. The flow properties of these fresh mortars closely approximate the Bingham model, whatever the time after initial mixing may be. When used alone, the polymer decreases the plastic viscosity of the mortar. When used in combination with sulfonated melamine or naphthalene formaldehyde condensates, it decreases the yield value.
