Synthesis and Modification of Polycarboxylate Superplasticizers—A Review

Materials
The molecular-scale structural changes in polycarboxylic superplasticizer (PCE) can influence dispersion and water retention. Polycarboxylate superplasticizer, synthesized using different methods, may alter dispersion and water-reducing effects. The synthesis of PCE involves creating a novel macromolecular monomer with a controllable molecular mass ...

Effect of cement fineness and polycarboxylate dosage on the rheological and mechanical behavior of a mortar

MATEC Web of Conferences, 2018
The use of certain organic additives in the production of mortar and concrete influences the workability and the hydration kinetic of mortar. This results in a modification of some properties, namely rheological behavior and mechanical strength.
