The results of investigations on the influence of superplasticizers based on sulfonated melamine resin (SMF), sulfonated naphthalene formaldehyde (SNF) as well as acrylic polymers (AP) on the rheological properties of cement pastes from different cement have been presented. Rheological studies have proved that superplasticizers based on sulfonated melamine resin and sulfonated naphthalene formaldehyde to produce the lowest fluidity of cement pastes in the initial hydration stage, whereas pastes including acrylic polymers have shown the highest degree of fluidity.
