A low-shrinkage and viscosity-reducing polycarboxylate superplasticizer was synthesized with maleic anhydride (MAH), diethylene glycol monobutyl ether, and methoxypoly (ethylene glycol) methacrylate

lignosulfonate, which is a natural polymer. The commonly used Superplasticizer are SMF, SNF, PCE. Plasticizers are added 0.1 0.5% by weight of cement whereas superplasticizer are added 0.5 3% by weight of cement. WHY WE NEED SUPERPLASTICIZER FOR CONCRETE?

What is polycarboxylate superplasticizer (PCE)?
Polycarboxylate superplasticizer (PCE) is a common admixture in high performance concrete. In the design of PCE molecules, it is necessary to ensure that the molecular weight of the polymer is moderate and the acid-ether ratio is appropriate to improve the dispersion effect.
Are advanced superplasticizers based on polycarboxylate polymers?
Advanced superplasticizers, which are based on the family of polycarboxylate polymers (PCEs), have been proposed in the past decade [11, 12, 13, 14].
How are polycarboxylate superplasticizers synthesized?
In this work, a series of polycarboxylate superplasticizers (PCEs) were synthesized via copolymerization using a novel macromonomer, ethylene–glycol monovinyl polyethylene glycol (EPEG). The molecular structures were modified by varying the side chain length, carboxylate density and integrating sulfonic group.
What are the advantages of polycarboxylate superplasticizers?
Compared to traditional superplasticizers (such as naphthalene sulfonate and melamine sulfonate), polycarboxylate superplasticizers have the advantages of low dosage, a high water reduction rate, excellent dispersion performance, and environmental protection [16, 17, 18, 19]. In addition, they can improve the quality function of concrete.
Does polycarboxylate superplasticizer affect thixotropic properties?
Ke et al. studied the effect of polycarboxylate superplasticizer on the fluidity, rheology, and thixotropic properties of a low water-to-binder ratio cement-silica mortar slurry, and found that it had obvious dispersion advantages for cementitious materials.
Do polycarboxylate superplasticizers affect adiabatic temperature increase?
The effects of the hydration products and micro-morphology were investigated, and the effects of the polycarboxylate superplasticizers on adiabatic temperature increase, early drying shrinkage, and the mechanical properties of concrete were explored. 2.
