Progresses in Synthesis of Polycarboxylate Superplasticizer
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 water retention as well as enhancement in
Synthesis and Properties of a Polycarboxylate
Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (35) The
Research progress on polycarboxylate based superplasticizers
Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
Polycarboxylate Superplasticizers - Concrete Construction
Subsequent to the introduction of so-called general purpose PCE superplasticizers, new PCE products have been developed especially designed to provide high early strength and different levels of slump retention, as well as provide different capabilities to manage air contents in concrete.
Polycarboxylate Superplasticizers Market
Short Description About Polycarboxylate Superplasticizers Market: The global Polycarbolate Superplasticizers market size was valued at USD 5641.68 million in 2025 and is expected to expand at...
- 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 cross-linked polycarboxylate superplasticizers?
- In this context, a series of cross-linked polycarboxylate superplasticizers were synthesized using acrylic acid, methylallyl polyoxyethylene ether and four different cross-linkers containing ester groups, respectively.
- What is polycarboxylate superplasticizer (PCE)?
- Masoudi Soltani et al. formulated polycarboxylate superplasticizer (PCE) through the synthesis of poly (maleic anhydride) utilizing maleic anhydride, sodium methyl methacrylate sulfonate, and allyl-derived polyethylene glycol (PEG) as source materi-als, employing ammonium persulfate as the initiating agent.
- Does polycarboxylate superplasticizer alter dispersion and water-reducing effects?
- 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, adjustable lipophilic, and hydrophilic moieties, as outlined in this study.
- Are cross-linked sustained-release polycarboxylate superplasticizers a good alternative to comb-type poly carboxy?
- Cement system properties (adsorption, hydration, compressive strength etc.) were determined. Cross-linked sustained-release polycarboxylate superplasticizers (SPs) are superior alternative to the comb-type polycarboxylate SPs due to they offer both a high fluidity and a good retention effect for concrete slurry.
- Can Polycarboxylate-ether-type superplasticizers improve the performance of cementitious systems?
- The objective of this study is to link the molecular structure of polycarboxylate-ether-type superplasticizers with the performance of cementitious systems in order to develop new products with enhanced properties, e.g. improved water reduction with a wide range of cements or a reduced retardation of cement hydration.
