Rheological behaviour of cements mixed with polymeric latices

Atzeni, C. / Massidda, L. / Sanna, U.

AbstractThe rheological behaviour of cement systems modified by adding polymers is studied. Acrylic, vinyl and epoxy polymers have been tested. Rheological measurements of the pastes were performed in a coaxial cylinder viscometer while workability of the mortars was evaluated by means of the slump test. The behaviour of the different systems reveals that acrylic latices have a strong plasticizing effect in some cases comparable to naphtalenesulphonate, while vinyl and epoxy polymers act as plasticizers only if satisfactorily mixed.
