Interlayer bonding investigation of 3D printing cementitious materials with fluidity retaining polycarboxylate superplasticizer and high dispersion polycarboxylate superplasticizer [PDF]
Proposed special requirements exist for the rheological properties and time varying characteristics of 3D printing cementitious materials (3DPC). In this study, high dispersion polycarboxylate superplasticizer (HD PC) and fluidity retaining polycarboxylate superplasticizer (FR PC) were used to control the rheological behaviors of 3DPC.

Tunable discontinuous shear thickening in capillary flow of MR suspensions [PDF]
Very concentrated suspensions of iron particles in water or ethylene glycol can be obtained thanks to the use of superplasticizer molecules used in cement industry. At high volume fractions, these suspensions show a discontinuous shear thickening which was thoroughly characterized in rotational geometries.

Progresses in Synthesis of Polycarboxylate Superplasticizer [PDF]
The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic‐lipophilic groups, long‐chain alkyl groups, and large terminal hydroxyl groups as well. Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and
